Simply awesome. This filter gave my already high MPG a boost. Glad to be apart of the K&N way now.
Gregory Bailey, Santa Maria, California
Great product! I noticed an immediate difference in horsepower and passing power. In my Opinion it's the best and quickest upgrade you can do for your car and can't say enough good things about K&N replacement air filters. Don't think about it, it's a no brainier, buy one. Just Don't forget to put the K&N sticker on the top of your air box so some unthinking service person doesn't throw it away. It took all of 5 minutes to install very easy upgrade at a great price.

This is my first time purchasing a K&N filter and I am very happy with my purchase. My car 2016 Civic (2.0L engine) definitely drives and performs better. Would mostly return to K&N products for any future purchases.

Great fit and super easy install. Really brought out the turbo sounds.

Makes the bypass valve louder than with the stock filter.

Spectacular, as expected. Nice to have the extra air and turbo spool sounds associated.
