do a stock airbox mod get and get a decent filter(comptec,k&N,spoon,ect... it will flow just as good as a short ram if not better. the password jdm power chamber intake is good for 20 hp, only thing is you'd have to swap in a k20 to get those gains. lol
parts list
94-01 oem ls intake box and pipe or any 96-00 TypeR - oem airbox, those work a bit better. Gsr won't work due to the length and angle of the intake manifold. DB gsr intake may work but don't quote me on that.
various parts from home depot and follow the insrtuctions below.

the pic isn't that great of an angle but the owner made a notch in the light so air could pass to the intake making a direct flow ram air. I plan on doing that to mine,I just need the time.
