I'm a 65 year old grandpa that refuses to grow up. I have used K&N filters on all of my cars, including my street rod/race car and my new 2022 Nissan Frontirr is no different. They breathe better, the performance is superior and the gas mileage is better. If you clean it and take care of it you will never have to buy another throw away trash filter again. I would definitely recommend this product.

Big difference from a cheaper competitor. My Nissan Altima usually gets 27-28 mpg. After installation I immediately increased to 31 mph. Vehicle is 2016 and has never had that high mpg since I owned it. Plus the dealer was charging me $99.00 for an air filter and installation. Save $$$ and gas!!!!

I use K&N filters in all my vehicles. This one passed qc but the inner metal frame is supposed to be covered by the rubber. On a 1/4 in by 1/4 in section, the metal is exposed.
