Review: Good filter... measure CORRECTLY - Make sure you measure the diameter of the hose/air intake you intend to install the filter on. THEN match it to the INSIDE diameter of the filter flange you order. I know, sounds like a no brainer. But I managed to screw it up the first filter I ordered. Otherwise the filter works fine.....
Review: K&N that speaks for itself - Perfect fit just what I needed for my project car. And has that nice sound to it now.
