so everybody likes this product but i don't see any HP gain reports from installing it can somebody show reports that you get better performance over stock intakes.
i have read that the stock intake is made to give the Eng. the amount of air the Eng. can handle any more AIR will reduce the HP .
I'd love to know what HP I'm making to the wheels. Along with getting a professional tune for better performance and a reliable speedo... Unfortunately, nobody within an hours drive of me does dyno tuning for 4wd/awd that aren't subaru's or ricers. Quite annoying. I'm sure there's somebody that's not too far away, but a man can only spend so much time scouring the internet and making phone call after phone call
