so the k&n can add more power and air than the gmppthink of a funnel. where the filter meets the heat shield/pipe the gmpp does not have it. with the k&n there is the funnel shaped ring that helps with smoother transition from the filter to the piping. pobably not much of a real world difference. but in theory you would think it would help a little. i think the k&n has a bigger filter too. but im not sure about that. apples and oranges really.
i definitely agree with that statement. hopefully you will find someone with an unbiased opinion, but i myself have chosen to go with the k&n.Everyone is just going to tell you to get what they have.. An intake is an intake.. chose one, be happy, call it a day.. But DON"T go cheap.. You get what you pay for!
