Customer Feedback

I drive a 1985 Nissan Sunny. Been using the stock paper filter for years, then I decided to change to K&N air filter. I'm using the screw on type of air filter on my carb. What I gotta say, better pickup and I like the sound produced when I rev the engine hard. Slight improvement in mileage but most importantly I know I'm using quality stuff and believe me K&N is no joke. Kinda expensive but this is one investment worth making and money well spent.

I was driving a Civic for 4 years before I sold it 2 years ago. The car is superbly fast in acceleration after I used the K&N replacement filter. My other friends on the same car model can feel great difference when they test drove my car. Now I bought a new Nissan Sunny, I am going to purchase a K&N filter as I strongly believe it will help its acceleration and petrol consumption!

I put a K&N in my 2004 Ford F150 FX4 right after I bought it. Nothing but great satisfaction with it. Averaged 22-24 mpg on the road. Not too shabby for a 4x4 with a 5.4ltr V8. The end of March, this year, I downsized to a 2016 Subaru Forester. Ordered a K&N the same day. Arrived in perfect condition and the car runs great. Have already noticed a pick up in power and better mpg than the factory states. I have nothing but great things to say about your product. Keep up the great work.
