Welcome! A K&N filter is a popular choice but will not do much in the performance category by itself. I would recommmend a C&L MAF system (cnlperformance.com) It replaces everything up to the throttle body, including an open air K&N. Check out the prices on ebay though because you can get one way cheaper than the $400 C&l is asking. I have one on my 94 gt and it works great. As far as throttle bodies, I recommend checking ebay again if you are okay with that idea. I got a three month old 65 mm for my gt for $75 compared to $200 retail. They make a slight to decent difference (I would say 5-10 hp at the absolute most, all at mid to high rpm's). It firmed up the gas pedal wayyyy too much for my liking though, I do not know if they all do this though. Just make sure to disconnect your battery before the install so the computer resets itself and you should be fine with no tuning problems.
