K&N air filter
Anybody have any opinions on K&N air filters and the claims of increased power and gas mileage? Thanks

I have one for my Ford Superduty. I now use it occasionally if my paper filter is dirty, until I can buy a new paper filter. It is a large hassle to clean and reoil for use. I haven't seen any performance upticks but it does a fair job of cleaning air. I have a bit more than 180,000 on the OD.
