I'm not familiar with it, but should be equal to most others by allowing a little more turbo sound. None of the CAI's will likely do anything performance related unless you add an aftermarket turbo too.
after a bunch of research yesterday, it only replaces the filter and housing, none of the rest of the tubing, therefore not touching the sound dampener etc in the stock crap. ive decided that it is not worth the money, to get the sound i want out of the turbo, ill just buy the aFe and be done with it.
