K & N and other Oiled Air Filters - FOR YOUR INFO

Here's a bulletin on oiled air filters that someone posted in a group last year.

This is a little off subject but before installing a K&N filter I would check out this site. It is a lot of reading but after I finished I took the K&N out of my car.

Great link. Thanks. Sure glad I never have use a K & N. the trade-off of air flow for more dirt is simply not worth it.
