when installing the gmpp intake do you have to disconnect the battery? also does anyone know if the intake is louder than stock intake... the only reason i want to buy the intake is to make the engine louder, so i'm hoping this will do it???

 

couldn't you, with the GMPP intake, cover the top part...then cut out the bottom?

so you wouldn't see the filter...and most of the air would be coming from underneath...if you don't do the hood scoop thing.

 

with installing the GMPP CAI whats the HP increase?

 

i wanna know that...wut are the HP gains..is the intake really worth it?

 

did gm modify the 2.2 engine a little bit in 2006? the intake stated that it is for the L61 2.2L
Will this intake work for the 2005 2.2? Also does it give better gas mileage?

 

Is crateenginedepot.com a good place to buy this intake and exhaust?

 

It's best to disconnect the battery so the computer can "learn" the new flow (this is also true of cat back exhausts).

Yes, it's considerably louder, and nice and deep toned. Since mine is sealed to the bottom of the hood and breathing through the scoop, it moves most of the "moan" to the outside of the car. You can hear it better with the right window down. But it's still quite noticable from inside.

 

since the GMPP intake clips onto the stock filter box bottom, if you seal the top it still breathes through the same (stock) intake in the fender that the stock air cleaner did. As for sealing the top, you can cut out the hood blanket and make a seal on the bottom of the hood to get a really good seal and then the hood will form the top of the air box. See my how-to on installing the GMPP intake (follow the link in my signature) for a how-to on doing this.

Note, however, that much of the restriction in the stock system is that plastic air intake thingie in the fender. I'd suggest removing it too. There's a how-to on that in the how-to forum, complete with a movie.

 

are u having any CEL lights since the install? also is the intake louder since you have a scoop or was it loud even before that?

 

No CEL, ever.

This kit uses a dry filter. GM seems to think that some of the problems with aftermarket intakes is with filter oil contaminating the MAF, causing a CEL (if the code is bad MAF, this is likely the cause).

When removing and installing the MAF, be gentle as it's somewhat delicate (don't bang it around or toss it in the toolbox!).

The intake was louder before the scoop (from inside the car). It's now louder from the outside with the scoop, and a bit quiter in the cabin. total noise is probbly the same, just moved outside somewhat. Still louder than stock, though, but not uncomfortable even on a long drive (where the drone could get a bit tiring otherwise).

 

Not to be a broken record here, but does anyone know the actual hp gain from the GM Intake? Thanks. And another thing. Has anyone found any CAI's for the 2.4L? I can't find any from AEM. Injen says theirs is for the 2.2 and 2.4, is that possible? (I don't know if there's any differences w/the intakes between the 2 engines) Because some CAI's say "2.2L" Only, like it wouldn't work for the 2.4L..... So if someone could clear this up a little better it'd be appreciated.

 

yeah wut is the acutal HP gain.

 

I don't know the horsepower gain for the GM intake, but to answer the other questions: The Injen intake does work for both, my friend has one. Don't knwo the HP gain, but there is a difference. Stay away from the 90 dollar JDM made CAI because it works like hell. I bought one to see what it would do, switch it around with my short ram and the stock. guess which one worked best? surprise, the one I have on now (short ram for those who haven't been paying attention) At least a 5 horsepower gain, or whatever number is usually noticeable enough... i say MAYBE ten for mine, simply because it allows the engine to breath better. LewiSS' intake should give the same increase because he did basically the same thing, only with a scoop. Using the GM Intake with the stock resonator... *shivers at the thought of that monstrosity...* You will see less power because of the fact you are still pulling through the EXTREMELY restrictive little black piece in your fender.

 

Not sure what you're talking about here. I went through the trouble of removing the air box in my fender thinking the same thing, but you will find that it is just a 3" mildly curved tube with a few side attached boxes that help muffle sound. The opening is right behind and below the right headlight where it can pick up fresh air. It is not that restrictive -- after I saw it I realized I had wasted nothing but time -- and I could not tell a difference without it even though I put some tubing in there and drilled some holes in my lower grille.

 

I have the 2.4L, but it shouldn't be that different of a part. I'll post pics of mine later, but it is big and burly to me. I'm used to smooth, efficient tubing, and the entire stock system is anything BUT that.

P.S. - All of those open areas create flow disturbance.

 

The HP gain isnt alot, i even saw somewhere how gm climed it didnt increase power at all.

But i have 2 questions
-If you install it yourself, does that void warrenty?
-Will it fit the 05s?

 

I agree - a CAI indicates that air is being picked up outside the engine compartment rather than the warm air around the engine. The stock system is a CAI - it just happens to be very restrictive (low flow filter, plus the resonator causes a lot of restriction). My system is CAI in that it is sealed on the hood and pulls in outside air through the scoop (the stock inlet and resonator is still in place as a back-up in case the scoop is plugged with snow or something, but air takes the path of least resistance and I'm sure, from the sound, that most if not all of the intake air comes through the scoop).

The same boxes and chambers in the resonator that quiet flow also causes a lot of turbulence, restricting flow (not to mention the size of the actual intake compared to a good cone filter).

 

Installation instructions list the 05 2.2 Cobalt.

It is a GM part and according to my service manager would not void my warranty -- I put it on myself. If you're not sure call or talk to your local dealer service manager. Keep the invoice in your car in case you take it in for warranty repair to prove you bought it through GM.

 

Thanks, but do I have to buy it through GM?

 

what if u buy through crateenginedepot.com?

 

CrateEngineDepot.com is a GM dealership -- Lattof Chevrolet. One of the best sources for Cobalt parts at decent prices.

 

After looking around, alot, I finally found some 2.4L CAI's!!!!!! Now, which do you all think would add more hp? The Injen CAI, or AEM CAI? I was kind of leaning towards the AEM.

I've heard many good things about the injen CAI. i've always liked injen, had one on my honda. it made it sound like a beast, not ricey at all. My dealership told me, no matter who i bought it from, if it was a GM Performance part, and as long as my dealership (or a GM dealership) installed the part, it would not void my warranty. If i installed it.... i'd be in trouble. then again, im not allowed to install anything beyond gm parts... *pfft* so much for that. i took her in today for an oil change (took off the ETD and RAI of course), and they gave me a 4 door SS model to drive... they will get up and run wont they? but my baby is still faster

 

how much do you think a dealership would charge to install the gmpp intake? i would install it myselft but don't want them to void my warranty since i installed and they didn't.

 

If they charge you more than an hour, they're ripping you off (IMHO). My install didn't take 2 hours, and that included the hood blanket mod and extra gasketing I did, and the time to take pics for the how to (not to mention having to hunt for every tool in my mess of a garage )
