Disappointed in Injen CAI
So I've had the Injen CAI for about a month and I'm pretty disappointed. I feel there is a significant loss in power in the low end compared to stock, heck I even feel like there isn't any gains in the top end either. I understand a CAI is supposed to give better top end at the sacrifice of some low end but again, I don't feel any top end improvements, if not worse. I'm thinking of going back to stock without resonator and just getting a K&N filter. Are there any dynos for stock without resonator with the K&N filter?
ps. I was running the icebox before and wish I hadn't sold it. Doh!!

Personally you have to just have to deal with it, and understand the air is being sucked through a longer tubing the short ram and even the airbox is a bit shorter.

A CAI on its own is mostly a superficial modification. It looks nice, and sounds awesome, but actual performance gains are minimal. Modern SPFI engines are tuned so well from the factory that there is very little power left that can be "freed up" by simple bolt-on modifications, which used to be the case with throttle body fuel injection or carbureted vehicles. No longer can a $200~ intake get you another 20+ lb/ft of torque across the entire power band. TANSTAAFL.
The most direct and effective way to get a performance gain you can actually feel is through tuning, which is especially true for a speed/density fuel system like the TSX uses (no MAF sensor so the engine cannot adapt to changes in volumetric efficiency on its own). The parts that Hytech offers promise good power, and with cams, a LT header and a tune, a high flow intake is going to show a lot more gains than it does on its own. Remember that you are starting with an engine whose breathing is choked off by a restrictive, mildly-cammed K20 head and stuffy OEM catalytic converter. I eagerly await the results of the first guy who puts down the cash for the complete Hytech system. We've seen how much potential this engine has.
Personally, the only powertrain modifications that I would do over again (in retrospect) on this car are the reflash, header, and high flow cat. I noticed their impact on driveability, but the CAI just made more noise. I wish I hadn't sold my Icebox too.

The stock airbox might not be that bad in the first place. A K&N filter might get you most of the gains to be had from monkeying around with the intake, but personally I dont even like the idea of using air filters that dont filter as well as the OEM paper one. (K&N's dont, and the off-brand one's I would guess dont either.)

Yep, there is a loss in low end torque. I think you can especially feel it on the 5AT automatic with the longer gearing. Since the gearing makes the car rev slower than the shorter 6MT gearing, you end up staying in the low end a little longer, where the torque loss is. Doesn't seem like the 6MT owners notice/complain about this as much as the 5AT guys.
With that being said, the Injen intake does sound nice though. It's a little loud, but some people like that, and also how mean it sounds. More people seem to get out of my way when I have that intake on....haha.
I'm actually thinking about doing a dyno with both intakes to see what the difference is. I'll be doing that and dynoing RT Hi Flow cat vs. 04/05 OEM CAT.
I wish I had an 06 CAT to test too. Anyone wanna loan me theres?
Hopefully I can hit the dyno soon.

I have a 6MT and I got the Injen CAI. I love it, works great with the manual. My only question is why do people want to get more power out of their TSX when they have it mated with a 5AT? The automatic transmission takes away a lot of power and it is very noticeable on these little 4 bangers. I'm not saying that they are wasting time and money, not at all, in fact the more power the better, but why start with such a low baseline with the automatic and then complain when the mods don't magically transport the car into a speed demon? If you wanted to have a faster TSX why didn't they just hold out a little longer and find the manual? I guess the answer to all of this do what makes you happy. Just my

.Technically an "emergency" car for the folks, even though they still have the MDX sitting in the garage. Like CGTSX2004 said, not everyone in their situation lets them get the MT.
