be careful about E-bay products. there is a guy selling "coolant bypass kits" and "timing advance kits" for SHO's and alot of other cars. This can be okay in some applications and yet a very bad choice in others. the coolant bypass essentially tricks the ACT into sending a lower temprature signal to your ECU thus shifting the fuel curve as if you actually had colder air coming into your MAF. This is what a CAI is intended to do. But since the air is not ACTUALLY colder it will cause you to run richer which can cause problems. Timing advance... Timing advance can be okay in small increments, and after doing some specific mods. However the kind of HP gains (20+) this kit states would push the timing advance to a dangerous level, causing your knock sensor to go bad prematurley and causing a myriad of problems in a few thousand miles. And who wants to by a new engine? Get the damn CAI and do your own timing advance. if i need it done i'll get a Ted Breaux LPM....
Running rich is ALOT better than running lean. At least being rich, you'll just foul plugs... leaning out will blow motors.
