djhiro, in the real world there are no gains from any intake only a sound change. Manufactures will make all kinds of claims but with our G35s they're not true. The Rev-up air box/K&N drop in filter is your best choice, Popchargers lose major HP due to their aluminum pipe design causing heat soak. (heated incoming air)

Hey guys thanks for the advice. I've got the rev-up airbox with z-tube combo. The reason I bought those two were mainly because your posts in the past Gary. I don't have the K/N filter, but I'm running an Amsoil one as now. Pretty pleased overall to say the least. Just wondering if there was any reason to change to a pop charger, but it sounds like there isn't. Will a K/N make that much of difference? Thanks.

Thanks for all the responses. It looks like I'm going stay with my rev-up airbox. When I had it installed, I put the rev-up airbox, z-tube, and motordyne 5/16 plenum spacer all in at the same time. So, the difference was definately noticeable. I know the plenum spacer was the major contributor to the change, but the sound was better with the airbox and the z-tube. If anyone has any other comments feel free to contribute. I was contemplating a K/N air filter, but it sounds like the Amsoil one I'm using is just as good. Thanks.
