I have purchased and used K&N Filters and maintenance accessories with positive results every time. Customer service is excellent with ordering and prompt shipping. I find that K&N products enhance performance and gas mileage. I use products on a 2004 Chevrolet Tahoe, 2005 Dodge Dakota, a 1990 Harley Davidson FXSTS and a 2011 Harley Davidson FLSTSB.

Until this purchase I was unaware you could purchase direct from K&N. All my cars, truck and motorcycles have K&N filters on them! No reason to purchase anything else, thanks for making such an awesome product. My 2013 Softail Slim is breathing easier now...
