the K&N ad in Car and Driver claimed that it'll put 11 HP to the G35...wonderring if that's true.

any feedback about the intake ?

 

Save your money, and the un-necessary wear on your engine by using a sub par air filter. Just just get a Z tube, a rev up airbox, and either keep your OEM air filter, or get an aftermarket dryflow OEM replacement filter. You can get all that for less, and get the same gains while maintaining the cleanest, and coldest air for your engine!
