The intake that you are talking about looks good compromise between Stock and a fully custom one. To be honest, I think (judjing only from the pics somebody posts) that most aftermarket intakes are not that well designed. It greatly depends on the full package setup, but that's the idea I get. Do you want something really good? Use 5efhe one, along with 5efhe cams and an rpm activated switch. Fit everything and do a couple dyno pulls to see the results and tune the rpm activation. I've seen over 20hp gain over stock intake, on a T25 turbo forged engine.
