Thread: INTENSE Fenderwell Intake Kit for 2004 Grand Prix

30 inches of 3.5 inch corrugated tubing with a 9 inch filter on the end.

I like the size of the filter.

Corrugated tubing might hurt air velocity, and it would additionally be slowed by there being a whole 30 inches of it. The fact of it being bent at a diameter of only 3.5 inches (instead of 4) might get someone's panties in a twist, but it's better than 3 inches.

At $99, the price is right, with all those pieces... it's about the price you could make that for, provided you prefer the $45 K&N filter over, say, a $25 Spectre dry flow.

For me, I'd say this is in no way better than just removing the airbox and strapping a 9" Spectre dry flow filter on the MAF. You'll save $75 and see the near-identical performance. Oh, and the filter will be slightly cleaner (needing less frequent cleaning) when it's in the engine bay instead of the fender.

I dont know if you're still considering it or not, but I just installed it yesterday. It was kind of an @$$ pain because of the narrow area you have to work with and the bracket that holds the lower part of the bumper in place, i ran the hose through that, though it barely fit, and you keep your original everything from the engine to the MAF, that curved tubing to the MAF makes things kind of a pain, i need to find a replacement for that, and I didnt' care much for the couplers they sent, i just used the original snake screws. I'm sure there was a much easier way to do it than I did. (Though maybe not, but I'm a novice mechanic still) After fiddling with it, and having some leftover parts, I got it all together, I'd say i'm happy. Its really the only mod i have other than a 180* T-stat right now, I felt a little extra pickup, and it adds a nice little extra growl when you're gassing it.
