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.

Great product does not hold moisture like paper filters and gets rid of dampness
