" The part arrived quickly and in perfect shape. I read the instructions, gathered the tools and then installed in less than a half hour, the only problem I had is that my hands are quite large and reaching back in to attach hose clamps was a bit rough.
All in a a perfect outcome." —Daniel S from Grand Rapids, MI bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 BMW 3-Series.
