[QUOTE="mike_123, post: 742844, member: 20063"] for what its worth i used to use k&n filters on everything my quads dirt bikes wifes car truck even my lawnmower and weed eater on my powerstroke deisle truck i had 2 filters and would swap out a clean one with every oil change clean the dirty one bag it and put it on the shelf for the next oil change after about 30000 kms of daily driving to and from work and towing my toyhauler i started noticeing really bad turbo lag took it into the dealer and the replaced the turbo wheel saying the fins were dusted this was caused from poor filtration i continued using the k$n filter in the truck as the added airflow kept the eg temps down while towing 20000kms later again with the turbo lag and back to the dealer for dusted fins this time however it was paid for out of my own wallet keep in mind i work on very dusty job sites and such now i only use oem filters on everything for a filter to let that much more airflow pass through it its gotta be letting in some forign matter pass through aswell [/QUOTE]
