I have a 2008 Coupe V6 and I was thinking about putting in a cold air intake system. I was wondering if 1) is it even worth the money? like will the performance/mpg/horsepower increase that much? and 2) what would be the best brand to purchase for this car?

I don't know much about CAI's but I think the horsepower is 2-5, mpg 1-3 and performance I heard was pretty good from other people who have done it, plus it is good for your car ;)

I have a 06 accord coupe and installed the k&n cold air intake and got 10hp gain from it plus it is definitly worth it adds more of a growl to the car and increases speed and if used properly can increase mpg's if i can stop punching it lol

I think a cai is a good mod and that K&N is a good company, but how do you know that you got 10hp from it exactly? Good to hear you're enjoying it - I have no doubt the sound and other improvements it provides are a lot of fun!

I was just using 10hp gain as an expression because you can feel the difference its not just a simple small gain, not as large as a turbo at or supercharger at all but more than just a spacer mod or mod of that degree

SEARCH!!! There are MANY threads posted in the 8th gen section about cold air intakes. Searching "intake" will yield great results.

Ok, thanks for the explanation. If your butt dyno says that's about what it is and you're enjoying it I can understand where you're coming from.

The K&N website states that the Accord with the 3.5L V6 will gain 10.23 HP @ 5217 RPM. That seems pretty decent and others seem to acknowledge that it makes a difference. My concern (based on prior experiences) is that my check engine light will come on after having this installed for awhile.

Manufacturers like to exaggerate their gains. You will not see a 10hp gain with any intake on these cars. With that said, don't worry too much about getting a CEL. Just be careful with the install. The only thing that can really go wrong is if you damage the MAF sensor. I had a CAI on my car for year and half with no issues.

Yeah you won't gain 10hp, simply isn't happening. However you will be able to feel a slight gain, especially on the V6 and with a proper install I wouldn't be worried about a cel. Your only concern should be hydrolocking

A Cold Air Intake is one of the best mods you can do to open up your car's performance. Think of your engine as an air pump, more air in and out = more power. Car manufacturers want their cars to be quiet.

I personally have an Injen RD CAI. AEM V2 is very well spoken of also.
It will NOT cause a check engine light and as long as you get one that is C.A.R.B approved you will not have any inspection issues.

There is a very noticible increase in power. However to get the most out of it you need to get the air out as well. Opening up your exhaust will be the other piece in your performance and fuel mileage plan. Down pipe, mufflers with little or no restriction, hi-flow cat, all will help a lot.

Our cars respond very well to these types of mods.

Have fun and be safe.:thmsup:

Performance gains will be marginal at best. The engine torque target will be unchanged as the ECU will still run the same program.

Do it for the acoustics. :thmsup:

So you guys actually thing you'll fell 2-4hp? No The gains aren't peak. The 10 hp is right where you want it. In the mid-range. 2-4hp is right at peak which youre not gonna be at 24/7 or you will indeed not gain mpg's. Import tuner and other mags indeed get 10hp or even more on cars depending on the motor they are testing. Some cars have crappier stock intakes than otheers. But you can bet the J-series V6's gain 10hp +. Just like J-series motors gain a lot from j-pipes or headers (15-30hp). Spend cheaply on ebay intake. you bed you'll get little power. Spend decent money for say Injen, AEM V2, or Takeda and get 8-12hp and 10-15tq. HP isnt every thing. Low-end to mid-range tq is the most gain you feel.

Have any dyno proof or just a general statement? A cai is a mod that just about everyone does, they're not that great in terms of gains on the average car. Many people just like to think they got more power than they did because of the money they spent. More air in and out equals more power? Little more in depth than that. You could have a huge open 4 inch piece of pipe coming off you intake, your not going to get more power, they amount of air being allowed in is limited by the throttle body and the amount the engine can flow in and out isn't really increasing. Now colder denser air is different. I agree opening up your intake and exhaust will obviously have some gains, just not as many as people think. Some people take the claims from the manufacturer and add up their cai and catback and claim they gained 20hp when in reality its like 5-10, again on average cars.

Your condensending attitude is offensive. I have a 03 V6 6speed with extensive bolt on mods. My car which I've had for 8 years is WAY quicker than a stock V6. I have outperformed G35's, 250Z's, BMW 3 series, M4's Mustang GT's and just about everythng else out there other than some F.I. cars & some V8's. Please don't tell me our cars don't respond well to intake & exhaust mods.
I see you have a 4cyl. you probably don't even care about performance or you would have bought a different car.Thanks for playing, "tell him what he won John!!" :D

Ha Ha... So well said bro. All I can say is AMEN. If he thinks we buy 2-300.00 intakes to make noise when we can do that free by removing the intake resonator to do that. The answer is NO we dont spend our hard earned money to get more noise. hahaha...

I don't think that making an otherwise correct statement is condescending.

The way a modern engine is built and programmed, a CAI should have minimal impact on performance. If it does affect power significantly, it usually mean the MAF is not reading the correct air flow and the engine is probably running lean.

That is bad mainly for emmissions but can also damage certain componnent on mid to long term.

I Disagree: When the MAF sees more air it will add more fuel (to a point), thus more power. Our Honda computers are very smart, they wont run lean N.A.
F.I. is another matter. I know many guys with bolt on mods, been to the dyno, air/fuel ratio good, and made a lot more power. I have NEVER heard of any lean issues or damage from bolt on's in our cars.:wave:

The MAF is only measuring a fraction of the airflow going through the intake and it is calibrated using the complete intake assembly.

The extreme example would be to tranplant the MAF in a 10in diameter tube. Thw MAF signal would be meaningless as it only "feels" the air immediately around itself.

The air flow behaviour will be different with a CAI or SRI. It has to be if any change to power are claimed.

The ECU is smart but it is blind and cannot recognize a change in intake configuration.

Like I said in a different topic, this is taken straight from the guy who calibrates OEM ECU. Intake mods are "less safe" than exhaust mod because the ECU can be fooled that way.

Not to say any given engine will blow up because of a CAI. Simply a heads up on what it might do.

As for the gains, the numbers seen are really close to the dyno's actual resolution. From run to run, 1-2% variation is common.

A bolt ON mod needs to yield a lot more power in order for us to reliabily say it is effective.
