Just take out the whole stock air box and put a cone filter on the rubber part like i did. the gain is the same and the rubber stays a little cooler then the aem one. cost me 9 dollars...
This is generally true, though when I went from my jury-rigged setup to the official one, there is a noticeable difference. Was the difference necessarily worth the money? I don't know. BUT my jury-rigged setup's filter was rubbing against my battery, and I don't like that. The official one has enough clearance to not touch any other part of the car.
