I know the 6637 is the preferred intake. Any other more elegant options that provide equal flow?
Don't want to increase whistle or noise if I can help it.
Thanks for any tips.
They all make noise. I think they sound cool, to hear that whoosh when you get off the pedal. The 6637 is your best economical bet. I had one, but came across a great deal on an AFE - so thats what I run now. I think the AFE is actually louder. And no real noticable improvement in performance either. You cannot get around the whistle - thats the turbo. But you can get around the whoosh and the infamous surge by installing an ATS housing...which I plan to do when money allows.
