That www.procarparts.com site that said they had 3000GT clear corners also had an adaptor to mount a K&N cone filter for 20$. This and the filter would be much cheaper than the FIPK or the Aircharger for that matter. Is it worth it? Also, this must be asked a LOT, but when I'm removing the resonator, the FAQ suggested a vitamin cap....waht if I don't have one? Will like a plastic screw on cap to an OJ bottle fit? it's roughly the same diameter, but it isnt as long on the sides. I'm just worried it'll get sucked up or leak....thanks for your help!
