Just finished putting on my K&N FIPK. Very easy to put on and as soon as I pulled out of my develpment to test it out, an evo flys by me. So I floor it to catch up and first thing I notice is my supercharger screaming. So we turn onto another road both gun it and he gets traction I don't at all but even though I wasn't getting traction I was on his tail the whole time. I love these cars.
