Air Intake Question

I have a 2002 Grand Prix SE

I was wondering... The air intakes on both GT, GTP, and SE's look the same... now i've been told you can't put a K&N intake system on mine without making it custom, becuase the 3.8 liter models don't fit it.

Is this really true, I can't see why it wouldn't work, and if it doesn't work why doesnt it?

Only thing I can think of is the SE and GTP's air flow ammount is different...

Please someone help me.

Are you referring to a K&N Aircharger type intake system or similar? The primary reason is the size of the throttle body. The SE/GT with Series II 3800 normally aspirated has a 65mm and the supercharged GTP has a 69mm. The throttle body size on a 3.1 SE is much smaller at around 58mm. You'll need to find a way to adapt the rubber ducting to the input of the throttle body as far as fit.

Well if it's 58mm throttle body what do you suggest I do... I need to find somekind of kit to fit my Prix... I'm not replacing the engine with a 3.8 till my current engine is in need of a funeral.

Does anyone have any ideas on this one, such as another vechile that has a 58mm throttle body and uses a K&N intake system... I'm in desprate need please ^_^

BTW thanks for the deminsions, helped me out.

the 3.8s do fit the K&N intake systems. They sell several different styles. I personally made mine. here is a link to the custom. http://grandprix.net/upgrades/intake.html

and hereis one for the ones that are ready to install there are like 3 different kinds on this page for the 3800 engine.

You are aware he has a 3.1L SE and not the Series II 3800.

Also, a 3.1 SE owner has to consider getting the rubber intake ducting properly mated up. The MAF sensor on a 3.1 is located between the air box and throttle body. The MAF sensor is not mounted on top or within the throttle body like on the SII 3800.

whoops----- I did not read into the question enough. I seen 3800 and didnt realize he was talking about a 3.1---sorry

You might try just buying the kit on ebay for the 3.1L and switching the filter out to the 9in K&N, that's what I did on my SE (2002). The only problem is the the "brain" computer is the old air box.
