K&N 33-2443 Air Filter Product Reviews

Monday, April 18, 2016 - Part 33-2443
I have been using K & N filters close to 40 years now, on my off road motorcycles to all of my cars and trucks. I value their products and when we bought our new Toyota Highlander earlier this year, the first thing I did was order a new K & N filter for the car. Changing it out from the factory paper filter was a breeze, took all of a couple of minutes. I will never change my practices of using K&N air filters.

Simply a great idea and well manufactured product. Third filter (on 3rd car) and can't say 1 bad thing about them.

Perfect fit on our new Toyota Avalon. Looking forward to better economy and a million miles of driving. We have used K&N filters on our last 5 cars and we would never go back to the paper filters.
