K&N Air Filters Reviews


K&N FOR JAGUAR X-TYPE

Reviewed By James W. C (Littleton, MA) Reviewed for a 2009 Porsche Cayenne —2/16/2007 5:35 AM

I make a point to purchase a K&N filter for every vehicle I own. I experience better engine performance, fuel economy and the convenience associated with a permanent filter, which equates to a cost saving by not having to constantly replace paper filters. K&N fileters are well made and their performance doesn't degrage with use/age. I wish K&N would offer a replacement pollen filter for my x-type Jag.

Let your engine breathe

Reviewed By Craig J (LUTHERVILLE, MD) Reviewed for a 2006 Acura TL —1/13/2017 8:46 PM

K&N has one of the best air filters on the market I have run them on motorcycles and cars and trucks for decades the easier you get air in and out of your engine the more power you can develop plug up one of your nose holes and try to breathe that's what I'm trying to explain one nose hole plugged is your factory system acts like let them both open that's how K&N works get it I hope so they make great products for the power guys and gals
