Always satisfied when buying K&N products. I would like to have an air filter and fuel filter for my motorcycle, 2015 Kawasaki Vulcan 650 ABS .

Had my pro mechanic stepson change the oil and install the new K&N oil and air filters. I gave him the K&N hat to wear at his job. He needed a special tool to change out the gas filter so it didn't get done until the next day. WOW He showed me the old filter. It was disgusting. Now the car accelerates better then ever before and is running great. I love K&N products and will definitely order again. Buying a 2013 Ford F150 STX next week. Can't wait to check out the available K&N products for it. Thanks -Tom
