This is the 3rd K&N that I have purchase...
This is the 3rd K&N that I have purchased as I just purchased a “new to me “ car and it had one of those paper filters. So that needed to be upgraded. My 2 previous vehicles had K@N filters. Clean and oil once a year for the life of the vehicle and never have to worry about replacing the air filter again. Installed in minutes, dropped right in. Nice value, fast shipping. These perform better than the average paper filter does as my experience has shown.
