HAHN vs. Injen vs. AEM vs. K&N
I'm looking into buying a CAI for my 09 Cobalt SS t/c. I heard that Injen was the best for the s/c but no recommendations for the t/c. Any recommendations? What is the price range for the HAHN? Can't really find a place to buy HAHN online. Thanks in advance!

Ltft and stft are the difference. Get the intake and no tune = fucked up fuel trims that can eventually lead to gas mileage, poor performance and maybe even a broken car.

The BPV sound from the K&N is very prevalent from my experience. The IAT's are also very close to a cold air intake setup and the spool time is quick as well.

the main difference between the k&n and hahn is that the k&n is a short RAM intake pulling air from inside the engine bay area where is hahn is a cold air intake and hangs down lower pulling cooler air from below. Like people are saying...u will need to tune. This isn't something u can just slap on...well u can, but ur car.might not like u...lol

I got K&N intake and its pretty good. I will say though there is a new intake coming out by BYT, BackYardTurbo, and its a "stealth" intake that can be modified to be a SRI or a CAI. He's also doing "stealth" charge piping. Might wanna check that out. Not sure if its final production yet or not, I know he's got a mock up on his car now.

I live my k & n intake. The bpv is so loud now. I'm untuned for over 10 k miles and have had no issues, no cel, and I just love how loud it makes the whistle of the turbo and the sound of the bpv

I'm running a k&n with gms1 and a hi flow catted dp.
I love it! My fuel trims never jump higher than + or-5 and usually sit more near -1.5and0
It fluctuated for a couple hours at first but has been golden ever since. Also it has allot to do with your filter position.
Order of mods if your lookin for power are
Downpipe
Intake
Tune
You could just do a mildly aggressive tune and people are seeing 295-310whp and 330-320-340wtq
That's JUST a tune.
Of your short funds tunes are no more expensive than intakes in some cases.

I'm sorry, but what do you mean by turning the filter?
