k+N dynos all their FIPKs for the specific vehicles.... they send the graph with the intake... for the 2.4, it gains 15.94 WHP at 5900 RPM

 

I think there was an argument about the dyno graph for the K&N intake. People were saying that the numbers were messed with cause its "impossible" to get those kind of numbers just from an intake alone. Ah but who knows I don't think anyone has dynoed their car with just the intake.

 

i dont think that there is a 15-16 hp gain i have the intake and love it but there isnt a 15 hp gain. i mean they dyno with the hood open which may give a few more horses on paper but i dont feel it, maybe a slight difference but that is it 5-7 hp and like i said before that goes for any intake i dont see how you can get that much out of an intake with a n/a 4 cylinder.

 

I see in your signature that you have the GMPP intake. Do yourself a favor and look into modding the intake by replacing the TB part with a Spectre 3" elbow and a short 3" tube. I'd bet you would hear and feel a difference. Because of the small opening in the GMPP TB tube your 2.4 is gasping for air above 5K -- makes it take longer to get to redline because it acts like you are part throttle, having to suck through that small opening. I like the looks of the GMPP over all the other intakes but as it is it is not the best for performance -- try it, you'll feel and hear what I am talking about...if your game, you will need to get a 2.5" Spectre hose coupling (your choice in color) and cut a 9/16" piece off. Then warm that piece in hot water for 5 minutes then take it out and fit it over the throttle body -- this will allow you to position the 3" ID Spectre 90 degree tube on the TB and clamp it down. You will then need to cut a 3" piece of pipe to connect the 90 degree elbow to the GMPP tube -- You will have to get a 3" X 3" coupling -- the Hump Coupling of the GMPP intake won't fit over the 3" pipe.

Larger exhausts make more noise. I'm at the limit of the law now with the 2.75" exhaust. I can assure you if it's all about flow -- the larger the exhaust the larger the flow...this is not rocket science.

 

I can definitely hear my GMPP intake. Not sure why you couldn't hear yours? *shrug*

Hmm I should try that my self.

 

That plastic lip that holds the filter breaks easily on the GMPP intake...

 

Yes it is hard to believe the dyno graph that comes with the K&N intake -- compared to the GMPP intake I do believe there is a large difference in performance above 5000 RPM. With the K&N intake my 2.4 goes to redline very quick. With the GMPP intake it felt and sounded like it was only part throttle.

I couldn't hear it over my exhaust -- with the K&N intake I can now hear the intake over the exhaust.

 

Thats not always true...if the pipe is too large the exhaust gases will cool down and slow down. They key is finding the sweet spot, not too small but also not too large.

 

Mine is at the sweet spot right now...

 

i have the GMP intake and i only got it because i got it when i bought it from the dealer. As other intakes my friend has the Injen one and is pretty satisfied with it. However i am not sure if they have one for the 2.4L. It doest really matter for me anyhow because my intake will be coming off over the spring or summer when i buy my hahn turbo kit. So what you have to ask yourself is if your going to go that rout or not. Because if so you may as well just wait.

 

tsk tsk larger does not mean louder at all, your muffler dictates the sound

larger is not always better, and your right this isnt rocket science its the thermal dynamic properties of gas we are talking about

 

does anyone know if the K&N will take your vechicle out of warranty? i asked the guy up at the pontiac dealer and he said it would but he was a *******. he didn't even know what it was at first until i explained it to him.

 

The only way a modification can void your warranty is if that part itself caused the failure and they can prove it.

 

It also depends on the guy calling the shots at the dealership. My dealer probably wouldn't void my warranty if I had a K&N intake and blew a piston. But the next dealer down the road would.

 

ok cool. see thats what i thought but the guy at the dealer made me question myself lol. i had to go up there to get another remote programmed

 

I had to do that. Between buying the new remote and getting it programmed it cost me over $100. This is why I really try to do all my own work. Either stock or custom. As far as the intake though you should be fine. Hell I went in with my catback exhaust and intake on and they replaced my catalytic converter under warranty. This was before I bought my aftermarket header/ downpipe.

 

i know this is alittle off topic but i'm buying a K&N intake from another member but its the 2.4 version, will i have problems installing it on my 2.2 or is it the same?

 

I don't think you will have a problem installing the 2.4 K&N intake on a 2.2 when it comes to the parts fitment, however, the TB is positioned a little further away (TB on the 2.4L is centered on the intake while the 2.2 TB is offset slightly to the drivers side). i can't remember the difference -- something like 1/2" -- but it could be enough that the tube won't be as secure to the base. Might be worth a try.

If you have a warranty problem with a K&N filter -- there is a 1-800 number K&N provides and tells you to have the service manager call. Supposedly they will work out any warranty issues for you -- K&N FTW!

 

make sure ur 2.2 doesnt have SAI or it wont work

 

cat-backs dont void the warranty anyways. I talked to the dealer and anything from the catback is fine. GM just doest want you to change the cat apparently. Thats why when you get a high flow cat you get that check engine light. Ait intake doest void your warrenty either. The only way anything can void your warranty is if it was proven that the mod you added to your car was the cause of any damage that may have occured.

 

Actually if GM was smart they could say the warranty was void from being over rich from the mods. If you got it tuned and then tell them that, you voided your ECU and electronics warranty. That's if they look deep enough and want to nail you for something as small as an exhaust or intake.

 

Just swapped my GMPP for the K&N. All I can say is wow! I wish I had installed this one from the beginning. I can't wait until the weather clears up to really let this thing out!

 

good to hear you like it

 

Now you see - and feel - what I mean! Clearly a difference in performance.

 

The only thing they're really gonna void is the warranty on the cat. Which obviously if you upgrade it you aren't gonna want a stock one back in there anyway. I'm not talking about having an aftermarket header/downpipe but even with a high flow cat its an easy fix as far at the check engine light. Also thank you for restating what I said 3 posts up back to me about the warranty. Also as slowswap said if they really want to be dicks about it they could turn you away.
