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.

Honda Civic '94
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!

Third application on a Nissan Titan. This time is a 2015 4 x 4 crew cab Pro 4X. Again, another great product courtesy of K&N Filters.
