K&N 33-2786 Air Filter Product Reviews

Thursday, January 19, 2017 - Part 33-2786
I'm a K&N believer I guess and all my cars... with the exception of my Land Rover 90 V8... because you don't make a filter to fit it... have K&N filters as a matter of course... I just like the noise and believe I can feel the difference in acceleration...just make a filter for my 90 and I'll be even happier!

Noticeable improvement in throttle response over stock; look at coupling with aftermarket air intake tube (not a whole kit) and you're about 15 hp ahead.

Experience was excellent with the K&N product. Exact replacement for my 2007 Porsche Carrera. Plan on purchasing air filters for my other vehicles.
