Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up. I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder. It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.

If you keep your vehicles a few years this will save money

I have been using K&N for 50 years very good quality over OEM filters and it gives your engine better breathing. Saves money over the long run.

Can’t go wrong with KN

Been using for years in all my vehicles. One time pricey but then years of trouble free performance enhancing filtration for your engine. Five minutes to install on 24’ Honda Pilot.
