K&N air filter
 

Installed one about 4 months ago. Was curious on how to clean it. Do I need to purchase the 15 dollar bottle of cleaner or will light soap&water do the job?

409, fantastic, or any all purpose cleaner will work. I've done it this way for 10 or so years.

Id use what is recommended, the k n cleaner comes with a cleaning solution u spray om then you have to spray that protective pinkish coating back on after its clean. And let it dry.

Not to change the subject but you guy's running these filters maybe could inform me . do these filters help as far as gas mileage and if so is it also necessary to run dual ex. I got a chevy 4x4 5.3 crewcab with 6 speed tran. i average 20 at 60-70 hwy. 12-14 around house. thanks for any opinions.....

If you don't put a more free flowing exhaust you just as soon stay with a stock filter. With true dual glass packs and k&n filter I got 2mpg more out of my Nissan frontier.
