Air Intake

What is the difference between the K and N 57 Series FIPK Air Intake and the K and N 63 Series AirCharger High Flow Intake Kit? Thanks.

57 is guaranteed hp gains performance with better materials to keep air cooler and is street legal. other does not do that well in some areas of build. the 57 is what you want.

I know that the only difference is that 57 is CARB legal and 60 is not. When it comes to functionality and gain, they are pretty much the same.

Well it is hard to tell now with details now gone from the web site. But typically the non 57 series used metallic ducting and was horrible at temperature isolation. They typically fell behind in performance behind the 57's. I think it was to appeal more to visual aspects while still giving some improvement but at a slight loss. I am not sure as to why the others did not get certified CARB. i typically don't recommend anyone that does not use high density polyethylene for its ducting. so much better at thermo isolation.
