since nobody has ansewerd this yet i will.......You don't see really big power gains out of it or anything, but it is rather beneficial fo runder hood temps. the driver side is right above the intake an dthe passenger side is right above the intercooler. so it does help with getting more air in there. so it's about as beneficial as getting a cold air intake instead of a regular ram air intake on some NA cars. helps with cooling, but no serious power gains. and the more air we can get to that intercooler the better. it's not like we get FMIC like everybody else so we need another way to get air circulation.
