Product Reviews

 Simple to install and slight MPG increase. Worthwhile upgrade on stock filter.
Steve, Venice, California
 No problems so far!
Joseph Maletta, Denver, Colorado
 Easy install - 5 min. and done. Thanks Ford. Ran K&N on '05 F150 for 160,000 miles - all good. Expect it will aid my Mustang. Just wish you made one for my '88 Ford Ranger SC 4x4.
Mike Peacock, Richmond , Virginia
 Love the filter. It completes having a K&N filter in every vehicle I own.
Barbara Holter, Colorado
 Great product.
Dean Little, Georgia
 Simply the BEST on the market. I have used them in all of my vehicles. They are easy to install and you will immediately notice a boost in power and a small improvement in the gas mileage. Easy to clean and very durable. Spend the extra money and try one in your car or truck. You will save that money the first year in gasoline. I have them in my 2014 Mustang V6 Coupe and my 2013 Ford Explorer XLT V6.
Stuart Hill, Deming, New Mexico
 Best filter on the market. This is the 12th car with a K&N filter and I will never use anything else.
