Hey AznDragon:
i know ZERO about cars, and i was able to install the AEM CAI on my GS-R without any major problems.
the first thing you need to do is jack the right front tire up and remove the tire. you then need to remove part of the wheel well cover to reach the intake resonator. there will be two 10mm bolts that are underneath. remove those and the resonator should come out. watch out for the tubing that attaches to the resonator and the fender (not a big problem).
under the hood, remove the filter cover with a Philip's head screw driver (the + pattern) and then remove the three 10mm bolts from the upper resonator. remove the rubber tube that is attached to the intake tube (before the throttle body). now, the problem i had was removing the bolt that holds the intake tube to the throttle body. i actually stripped mine and broke it. not a big problem, in my mind.
once you have all the stock parts out, attaching the CAI should be a piece of cake. just make sure you re-attach the tube that was attached to the original intake. i had to get another tube because the stock one wouldn't fit correctly. attach the filter inside the wheel well, re-attach the well cover, and put the tire back on.
to reset the ECU, follow this simple procedure. i got this from the old PH:
let the car warm up for 5-10 minutes, then turn off the car. Locate the Back Up fuse (7.5 amps) in the underhood fuse box and remove it for 5 minutes. Replace the fuse, and start the car and let it idle for a few minutes without touching the gas pedal. Turn off the car, restart it, and drive it hard! This tip, which only works on Honda and other cars with speed-density fuel injection, resets the computer and allows it to "re-learn" the engine with the new modification in place. Good for a few extra horsepower.
hope this helps.
