I'm considering doing this mod.

No issues with sucking water into the filter, engine,etc?
I saw one kit had a bypass valve kit?

other kits don't offer this?

It's always a possiblity. I would say you are better off with an intake that has a bypass valve. Better safe than sorry.

Or, take the resonator off and stick a 3" piece of flex pipe on the air box and route it where the cold air filter would sit. You'll never have to worry about water and still reap the benefits of "cool" air. :thmsup:

Wow! Not that a CAI provides a huge power gain, but does this mod provide a similar power gain. Definately a clever idea. :thmsup:

Would that also provide an increase in fuel efficiency?

I don't see why it wouldn't. It definately won't decrease power. I have it positioned where it pulls air in from the same spot as the Fujita. It only cost me ~ 8 bucks, too. There's enough material left to do your friend's ride also. I'm doing the same to my Mom's Accord when she gets to my house next week.

Fuel efficiency wise, I just got 32.5 MPG w/ 6500 on the clock. Thats using 5w-40 synthetic, too. It will only get higher w/ more miles and once I get some decent 5w-20 back in. I'm sure the larger exhaust helps some also.

I don't see why it wouldn't. It definately won't decrease power.
Good point!!

I may have to give this a try.

Did you just pick up the flex pipe at Home Depot or something?

Yes Sir. Its flex pipe ducting that you use on your dryer. Its not the squishy kind that you normally use. Its solid and takes some good squeezing to even put a dent in it. Its perfect for this application b/c its durable (for this purpose), cost effective, and it works.

Good Luck

Sure. I'm @ work till 2300 hrs so it'll have to be in the morning. Sound good Lex?

Cool. Thx!

Bottom of Airbox w/ hose attached

8189

Close up of hose. You can get it @ Home Depot, Lowes, etc. As you can see, I did it the lazy way and zip tied it on. I'll do a hose clamp eventually, maybe. Its been like this for 4500 + miles and w/ all the storms we've been having lately it hasn't failed me yet. The hose sits identical to where the Fujita filter sits.

In order for this to work, you have to remove the resonator (duh), and the rubber coupler that is attached to the airbox. I didn't do this next step, but I would encourage anybody doing this to do it. The plastic piece on the lower portion of the airbox that the coupler was attached to has a raised lip around it. Just use a file or small dremel to smooth it out. It will make the hose just slide right on.

After you remove the resonator, the airbox feels a little loose compared to stock. Don't worry, the 2 10mm bolts that hold it down do a fine job. Just snug them pretty good and your set.

Well done!

Thanks for the pics!

No problem. I didn't want to spend 180+ on an intake when I can achieve pretty much the same results this way. Plus, I'll be getting a spinny thing here in the near future to sit on top of my Love-Fab sidewinder manifold. :naughty: Won't be needing the stock intake after that. :thmsup:

spinny thing? the tornado?

spinny thing? the tornado :thumbsdow?

No, a turbo. Please don't waste your money on that junk.

Good idea with the flex pipe.

Appreciate it.

ill do that and maybe get K&N filter. untill i get AEM CAI

Just do it and not worry about the K&N. Your stock filter does a good enough job of letting air in but also filtering it @ the same time. Tests have shown that K&N's perform so well b/c they don't filter that well allowing dust particles to enter the engine more so than a paper element.

love fab sidewinder?

?lol huh...speaky enrgish

love fab sidewinder?

?lol huh...speaky enrgish

Its an exhaust manifold (for a turbo) that positions it to sit over the tranny area. Its called a SIDEwinder b/c of that. Most turbo manifolds just sit it directly behind the valve cover. Putting it off to the side means a Larger turbo.

That explain it enough?

Its not Love Fab anymore, its Full-Race sidewinder manifold. Sorry, I'm old school and that was the old company name.

I'm not trying to knock your idea here, but it seems to me that you are defeating the whole "Cold Air" idea. By still using the air box, you are still allowing the air to heat up. The heat from the motor builds up inside the box and therefore heats up the air coming in. Even though you have removed the resonator and allowed a slightly better air flow, it is still heating up. Now if you removed the air box completely and used your same idea but instead installed a round air filter to the end of the hose where it sits in the bumper, you would be doing the same effect of the CAI that AEM and the others sell. This allows the air to go through the filter while still being cool and then directly to the intake before it has a chance to heat up. Just my $0.02.

As for the OP questions, I have the AEM V2 CAI and I love it. I have not had any problems with water getting in to the intake even though it sits low in the bumper. The only way you would even have a chance of this happening is if you were to drive in to a large water source that is higher than your bumper. At which case you would be asking for problems in the first place. Driving through puddles that just splash up water have not caused me any problems. The bypass valve that you were also asking about some having and others not, this depends on which version you get. AEM's version 1 CAI allows for this bypass valve. Version 2 does not however it uses a larger diameter intake pipe for increased air flow. If you do go with one of these, the AEM V2 is the one that was recommended to me by my contact at the Honda Parts counter. I have not regretted the decision and I would recommend the same to you.

That doesn't make a whole lot of sense. The fact that the part exposed to the heat of the engine is made of plastic should actually make it more effective (though I'm sure it doesn't in practice). I guess what I am saying is that because most cai's are made of metal, they are going to be much more prone to heating up the air than the plastic airbox is. Metal conducts heat MUCH more effectively than the plastic airbox would. In fact, any heat that is absorbed by the portion of the intake up near the engine is going to be very readily transferred down the intake towards the filter, which seems worse to me. However, the fact remains that most home-made intakes simply do not perform as well as those designed specifically for the car, though this is not going to be because they are less prone to being effected by the heat of the engine, but probably more of an issue of turbulence if I had to guess.

People can have differences in opinions on here, thats why its a public forum. That aside, I see where your coming from about the filter still being in the same location. But, the air it is inhaling comes from the end of the flex pipe which is in a denser location than factory.

I am by no means saying this mod out does a V2 or the like, I did this to reap a little benefit of cooler air entering the engine rather than the factory location sucking air from up high in the engine compartment. It is doing something for the good. How much? Don't know, didn't dyno stock and then the flex pipe mod. Its just a cheaper (A LOT) way to see a little gain.

Just from touching the airbox before and after I can tell you it IS much cooler w/ the flex pipe. Thats not the placebo effect either.

That's a neat idea with the flex pipe. Good job.

The CAI gets its benefit from where it gets the air, not where the filter is. That is why the TL has its inlet down by the front left tire.

I would stay away from CAIs anyways. They scare me. I just replaced my air filter yesterday (stock) and it had water in it. Where did it come from I have no idea, but I'm guessing it was sucked up there from all of the rain we've received down here. Scared the heck out of me.

I would have to agree, the flex pipe is simply bringing in cooler air. This in turn should have a beneficial effect.

There is also no time for the air to heat up in the stock air box, so where the air comes from should make a big difference. I could see Coyote's point if the air had enough time to heat up, but the air is not sitting. Thus, in theory the mod should be bringing some cooler air, providing somewhat of a performance gain.

Thanks for all the positive feedback fellas. Like I said earlier, the pipe was only ~8 dollars @ Home Depot and you can do 2 like this with it. :yes:

Stevencrosbie, I know about the non-stop Texas rain we've been having.:thumbsdow When's it going to end b/c my front yard is turning into a jungle. But, the flexpipe hasn't failed me still with all this downpour.:thmsup:

Yeah, some parts of our yard are so swampy that we have to mow it with the weedeaters. The mower just sinks into the ground......

Hi guys, I'm reading up on CAI's to get a little more power from my I4 accord and this seems like a cool option. I have no experience modding cars and this is my first car so I don't want to mess anything up, anyone have any advice?

What would you say the benefits of this mod are (about how many hp?)

Any thoughts on doing something like this with the V6?
My box looks like it might be different.
Any links around with this mod for the 6?

Thanks,
Mark

Hello, CAI (CIA?LOL!) folks.

I've been learning as much as I can about CAI's. I have the 2005 Honda Accord V-6 Hybrid. I was in O'Reilly's Auto Supply today getting some Sea Foam to run through to clean the injectors and ran upon a display by K&N with a CAI. I got the book down to see if one would fit my car. Nada. It just went to the '05 Civics, in the 4 bangers, and that was it. Lost all hope.

I wish you well, markrb, getting one of these pups.

Take care, guys-

I was curious if anyone has thought of doing this CAI mod, and routing the end of the hose to the foglight grill, so as to make a ram air effect?

Just throwing an idea out there, does anyone think it would work better with ram air, or should I just leave it dangling in the wheel well.

Or better yet, there are little air vents in the wheel well that look like they suck up air from under the front bumper, and bring it into the wheel well, good idea or no?

I did turBeau's mod 10-07 because it made sense to me and the price was right. Pretty hard to tell if it made much difference with the old butt-dyno. Might be good for a couple of horses under the right conditions. It didn't seem to make much difference in sound either. Maybe just a little louder at wot. I had fogs, so the ram air idea wouldn't work for me. Seems like it would be a good idea. I have no worries about hydro lock. I figure I'd have to drive into about 12 - 16" inches of water for that to be an issue. I've never done that in my life and don't ever expect to. However, if you live in an area prone to flash floods, etc. you might want to mount the intake a bit higher. If you try it, let us know what you think.

I thought I'd add an additional tip to this thread. I decided to pull my air filter to see how it looked today. To my surprise I found 3-4 oak leaves (intact and in good shape) in my air box. I was pretty surprised they could get into that fairly well enclosed area in front of the wheel well, much less up the tube and into the air box. They couldn't have been helping my air flow! I ran some errands after cleaning them out and my car seemed a little perkier. Probably just my imagination.

Anyhow, it would be a good idea to put some type of screen over the end of the intake tube. I know I'll be doing that when I have a little more time.

spinny thing? the tornado?

Just a gimmick. Doesn't work. Had one installed on my Mazda3 I didn't see any difference. Sometime later, I read somewhere online, that the tornados actually restrict airflow rather than increase gas mileage/preformance. Needless to say, I took it off - I'm glad I spend the money for one.

what if you put one of those cone filters at the other end would that make a sound diff? Also that would basicly be the cold air intake , and you can also have the benifits of a paper filter if you still want.

I want to help address a few points about cold air intake systems.

The cold air intake system is successful in the method that air is taken into the engine. With stock intakes, there is a lot of turbulence that occurs with the air being sucked in. This comes from the same idea of the tornado's. Those are gimmicks yes, because they don't change the shape of your stock intake box and pipe. CAI's has smooth walls from end to end, therefore creating a smooth trail for the air to follow, without hindrances. This is a major factor for CAI's to be helpful to your car as well as the denser, colder air.

The fear of hydro-locking a car only exists if your entire filter is submerged (if you own a CAI), or if the entire hole of the tube is submerged in water in turbeau's DIY intake.

As far as the bypass valve, I have found some people to run bypass valves for years with no problems, but others who have had the filter actually break apart inside and get sucked into the engine. Needless to say, this is not good for the engine.

4IDrocca, the ram air effect is assumed to be better, but since it is not going to be a true straight pipe to the intake manifold, it won't make too much a difference. The cold air you suck in will be the best part of this modification.

ypsibird, i'm sorry to hear that you sucked up a few leaves. It's a good thing the entire filter didn't get clogged up or the engine may have shut off on you. Another idea to block up the open end of the pipe would be to put some kind of gutter guard over it, or some kind of mesh that could probably be found at Home Depot or Lowe's.

bmwproboi05, adding another filter could restrict flow of air to the engine. it would protect leaves from getting into the box, but would not necessarily be better for the DIY intake, or a suggestion to only run a filter on the end, since the open end of the pipe is not attached to any solid mounting, but would just be dangling. This could be potentially dangerous of falling off, and your engine sucking in any and all debris into the actual combustion chambers of the engine.

I've nearly hydro-locked my TL twice before, but have come out all right. The bad parts were when i drove into a VERY large puddle of water that came a little above the bottom of my door. Needless to say, a bad idea, but it was the fastest way home, and I realized it too late. lol.

Intakes are decent investments, but are not necessary unless other flow changes are made (headers, full exhaust, intake manifold upgrade, etc).

Just my $.02

I bought an intake off ebay and when it rained I use to just remove the bottom half of the in take and put filter in the middle where the pipe use to be and had short air intake. But I've never seen someone put this hose on stock air box.

Thanks. I eventually ended up just using some aluminum window screen I had laying around. Just wrapped it around and secured it with the bottom hose clamp. While I was at it I also raised the end up another inch or two. Mine is mounted pretty low.
But I agree with you about hydro-lock. For example I was on the freeway on a trip for about 2 - 3 hours at 70 - 75 mph when it was just raining buckets. I've got really good rain tires - few people were exceeding 60. No hydro-lock. But I will avoid driving into 12" + puddles!

i know someone else already said a comment or post about having a v6 having a CAI wouldn't matter but i couldn't find the comment again. Does anyone else have comment or idea for v6's and if the stock air box acts like a CAI or not?

No, the actual inlet is near the headlight in the engine bay.

There is a lot of controversy as to the value of a CAI. In theory they should help. In practice I doubt that they add very much. Just my opinion. But keep in mind that horsepower isn't cheap and you have to decide how much it's worth to you to add even a little. I only did my "ghetto" intake because it only cost me about $10 and an hour or two of my time. I hoped to get maybe 2 - 3 hp out of it. I can't say I can really tell the difference with the old butt dyno. Some people value a CAI for the sound value. Nothing wrong with that if it's what you want.

Your stock intake is just in front of your battery on a V6. There is a small plastic piece there held in by 2 push pins. The intake is just below there. You can easily pull the plastic cover off and look if you want. I'm pretty sure no one would consider the stock intake a CAI. Some stock cars do have stock CAI. My old Cougar drew it's air from the front fender outside of the engine compartment.

:thumbsup: Thanks for all the info

CAI or SRI will do it. I had a SRI on a stock Civic and mpg increase.

Just my 2 cents...

I did this mod on my 2003 Vibe when I had it.It was much better then the restrictive tubing that came with the car,I had a tube long enough to catch air at the grill opening

So installed turBeau's CAI set up today and played around with using the stock filter, no filter, stock filter w/ cone filter, and cone. Turns out the cone still makes the "sucking" sound like a regular CAI or SRI would. Of course its not as loud as a straight pipe and its doesn't have the "sucking" sound when car is idle but its still a tite idea! :thmsup:

No Fog lights so I plan on taking the vents out when i take it to the track so i can use it like a ram intake as well

http://i729.photobucket.com/albums/ww299/loveracing831/DSC02000.jpg

I did have to move it around a little more and used some zip ties to support it in the end but you can't see them unless you take off the fender liner

I also have a question if anyone wants to answer. I bought this accord used and do not have a drivers manual does anyone know what torque the lug nuts should be? I know most Hondas are 80 lbs. so just wondering if you guys use a different setting.

How would someone find out if they had MAF (mass air flow) in their car? i couldnt find it in my users manual... i think this is important for buying an intake right?
haha

$180? Try $289!

Anyhow your flex-CAI won't work like you think it will. The ribs in your pipe will create air turbulance where you don't want it, thus lowering power and mileage. Not a lot but enough to negate the mod.
