Takeda or Injen intake?

5237 Views 26 Replies 13 Participants Last post by  Fast4door
I purchased a injen cai a few weeks ago. The first one they sent me was polished when I wanted the black. I sent it back. A week later I received another one. This one was black but the injen label was completely in the wrong place. This is making me rethink my purchase. If they cant ship the right intake or get the one label right Then how good is injen's product? So maybe this is just a sign telling me to get the takeda intake instead. I don't know much about these intakes. Just got the injen cause it was the only one out at the time. I don't know if im going to keep the injen or send it back and get the takeda. So what do you know about these products to help make my decision easier. Thanks.

I have the black Injen CAI and I'm satisfied. Installing the Takeda will be easier most likely since you don't have to remove the bumper. Who did you order the Intake from?
I bought my Takeda a few months ago. The first one they sent, the tube was too long on the TB end and the mounting hole wouldn't line up. They sent me a new tube. It was fine after that. All of these products are made on a jig. They all can't be exact every time. What really matters is how the company resolves the issue. I'm happy with my Takeda. It was inexpensive and easy to install.
Can someone please explain to me how the SRI will increase performance? I understand how a CAI, with the breather end located in the fender, away from the engine compartment, will allow colder, denser air to reach the engine, thus increasing performance, but with the SRI, it seems the air that will be entering it will be no cooler than the stock intake, if not warmer, since the stock breather pulls air through the snorkel in the hood. Isn't the SRI nothing more than a noise-maker?

Larger air filter surface area for more air to enter. The air entering could be higher in temperature but ultimately more air is entering thus increasing power. The shorter intake path also increases response.

The higher temperature is a cause for concern though when outside temperatures get up there. Heat soak can occur and the engine/ECU will retard which decreases power.

This is a prevalent problem with aftermarket intakes since most intakes use aluminum intake tubes which simply gets too hot under the hood. I could not touch the intake tube on my Injen CAI on my 350Z after driving. It's that hot.

Some people may argue that the air is rushing through too quickly to get heated by the hot tube, but IAT readings never lie. The air does ultimately heat up.
^^ Pretty much SRI's are noise makers. In theory it enables higher air capacity to flow into the engine with lower turbulence, but I doubt the stock ecu takes much, if any, advantage of that.

And I won't rehash the argument, but a hot intake pipe doesn't make much difference. At cruising speed my intake air temp. is 10F or so above ambient, because it's hot in the engine bay not because the intake itself gets hot.

This assumes the stock system is incapable of supplying the needs of the engine, which is highly unlikely, and that the fellows who throw together these intakes better understand Helmholtz tuning than Honda intake design engineers, which is ludicrous. At best they make only a little less than stock power and more probably significantly less than stock power when hot. Their only real benefit is they allow more intake roar to come through.

Lol ignorant.....go look at my k24 injen intake thread. Go rethink. Proof is in the pudding.

Link? l'm open to and I'd love to see empirical proof.

Injen k24 intake

Only power mods are what i listed a catback and CAI from injen and almost identical weather conditions both after letting it sit for 30min before the pulls enjoy :) btw not attacking any of you guys that think CAI whp are bs. I went out and tried to get my own personal truth to see if the honda stock ecu can handle boltons properly without messing up a/f readings ....and i am very pleased with the results so far

Thanks with the link. So are your dyno results a comparison of stock vs the combination of the intake plus a catback?

Yeppers bone stock. New drop in oem airfilter. And second was both intake and catback Not that it makes a difference but both are ran on 93 shell vpower

Given that you changed two components for the second dyno test, it's impossible to allocate any particular portion of the gains you saw to the intake. That being said, the gains you reported are significant, and I'm impressed.

The gains you found don't happen in some motors tuned at the factory with a bias towards performance, and in fact in those motors your modifications would produce little to no improvement. For those motors big bucks on internal engine work is required to see any meaningful gains, and truly big gains require forced induction.

I guess the lesson here for me is that, for the Accord at least, Honda has made enough compromises in favor of reducing noise and increasing comfort that someone willing to give some of that away can pick up some useful horsepower with relatively simple and economical modifications. Like l said earlier, I'm impressed.
Ordered my Takeda Tuesday

Really interested to see the gains with this car! The addition of my muffler delete this could be quite fun! Tip out there for all v6 owners turning off the A/C when you can you can notice the power gain!:thmsup:

Go run a few pulls :)
How much Ora horse power would you even get from those intake? Swap k&n filter and your done?

lol what? look at the dyno charts on the link above
Well I just spent the last couple days researching intakes and comparing injen and takeda. Injen claims 8hp gains and takeda claims 17hp gains. I seen the dyno charts from takeda. But the problem with them is when I watched the runs they had the hood up and a fan on the intake. Which basically took the negatives of a SRI away and turned it into a CAI. So I would say the 17hp gains is high. On that being said the takeda does have a heat shield and air is supplied to it from the resonator to help keep it cool. How much heat gets to it is the question. I couldn't find dyno charts for the injen. I would say they have about the same gains. If you want more lowend gains get the injen cause the SRI is going to **** hot air when sitting and not at speed. If you want high end gains get the takeda cause at high speed the air from the resonator will force out the hot air from around the filter. SRIs are also better at high RPMs just like ****ing air through a short straw is easier than a long straw. Now the hard part. I looked for sound clips for both intakes. I could only find a TL with a 3.5 with the takeda. It sounded great but it was in a garage with the hood up on a dyno. So that probably mad it sound louder than it really is. I couldn't find a good clip of the injen on a v6. I know pilotbear has some flyby clips I have heard but I couldnt play them for some reason. If someone has a link or clip of these intakes please post. I'm looking for clips outside with the hood up. From what I read CAI has a deeper sound than the SRI cause of the sound echoing down the tube. But you will hear the SRI better in the cabin cause the filter is closer to the driver. I'm by no means a expert an the subject. If you have something to add or correct me on feel free. But no need to be a jerk about it. I'm just trying to save some people some time.

Wasn't the pulls with the exhaust to? If that was with just the intake that is good for a I4.
