Customer Feedback

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 .

I had bought an air filter for my 2007 V-6 Suzuki Grand Vitara. I just returned from a trip to Nevada. The trip is 2600 miles. We do this every Spring . We keep good records of the gas and mileage. With the new K&N air filter we got 4 miles to the gallon more. Also I had a lot more power. Good product. I have a 2010 Ford F-250 with a Diesel motor. Do you make a filter for this motor? One that will not have to have any modifications.

Filter is perfect for the air cleaner mod on my Kawasaki Nomad motorcycle. A filter lid would be handy for this 10.5 o.d. filter. Your delivery time was AMAZING! One and a half days from California, WOW! That's very impressive. Thanks again for the great service. Roy
