The silicone sleeve used to attach the intake tube to the throttle body was a larger diameter than the throttle body flange leaving a kink in the sleeve when tightened. Intake tube had two pin holes at the parting line seams, one on each side, and the tube was not correctly formed to provide a flush fit around the throttle body flange. I have purchased K&N products for other vehicles but this is the first time I have seen poor quality like this from K&N.
looks great sounds great just installed it so waiting to calculate gas mileage, easy installation.
Overall great system. I noticed a minor difference in horsepower and gas mileage. Easy installation and instructions were spot on.
