Hey what's up, I just installed a k&N FIPK on my 99 sport the other day. I haven't heard anything like that whistleing You guys are taking about. I really didn't notice any performace gain either, I just noticed it idles a bit smoother and it a bit louder. Well hope you guys figure it out cause i'm sure it's annoying. The only thing i can think of is maybe there is a tiny leak where the MAF sensor bolts to that plate. My k&n kit can with 2 rubber gaskets to go in there. But i made sure that i tightened the bolts criss crossed so i didn't distort the plastic MAF sensor. A small leak is the only thing i can figure cause nobody says they get it at idle so my guess is when it sucks the air in at 1/4 throttle. Good Luck Guys.
