We bought this cold air fenderwell intake from Intense. INTENSE-Racing.com: INTENSE Fenderwell Intake Kit for 98-05 Cars
It took a couple hours for me to install but I could probably do it in less than half that time if I had to do it again LOL! I would have preferred an open cone inside the engine compartment for a couple of reasons. 1. easier to install and 2. easier to change/clean the filter. To get to the filter now I have to take off the wheel and plastic fender well. My son really wanted the cold air system so I caved. According to him and his friends the cooler air is better for the supercharged engine. idk... I have my doubts and I'm really looking forward to helping him get to and clean that filter now... Having said all this the car does get a mile or two better mileage now and does have much better throttle response. The original air box seems to be fairly restrictive. I do like the PCM mounting bracket that comes with the intense system however. It is a GM part and I feel better not zip tying or using Velcro to hold down the PCM. As far as sound goes my son loves the fast and the furious whine when you stomp on the pedal but I'm old school and prefer the growl of a big azz V8.
