Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

Spin tires on pavement is what this should be called. Great mod for the stock air box. Allows a lot more air to flow through and the sound is totally cool. Makes your GP sound like it should. I have no problem installing it, although you should take your time and using metal foil tape will further isolate hot air from the intake side. I put this on both sides of the metal and it actually keeps the hot and cold air apart even better. No realy change at lower RPM's but works great at higher revs. Just know that GP's come stock with rev limiter programming in place. Get rid of that, put this on the intake and free up the exhaust and you are doing well. Great product, all of my vehicles get this mod. Well worth the price and does not void any warranty.

I've been looking at this product for a long time and finally found this great deal on Amazon. I only had two problems with this product. One of the predrilled holes in a mounting bracket was too small so I had to bore it out with a drill and one of the hose clamps was the wrong size. The installation process was much more extensive than I had expected and the instructions could have been better. As far as the performance of the product, I was blown away. The power increase is definitely noticeable and now the supercharger sounds like it should. I am very happy with my purchase.

After installing this kit in my car, I noticed a big difference in acceleration and power in the higher RPM's. You'll also notice that supercharger screams when it's able to receive more air into the engine. This is the second mod to my 2004 pontiac GTP (Comp G), in addition to my 180 T-stat. My next mod is going to be a 3.4 pulley for the supercharger, which should put me right at 300 HP. Sweeeetttt!!!
