I got K&N "Reusable" oiled Air Filter because of the price used. One for free & second one for around 20$ or so. Lifetime warranty make me feel warm & cozy.
Im sure it will wear & tear down the road of many cleaning, wedged pieces rocks & particles between the pleats.
Cleaning solution & protection oil for the K&N Air Filter can get expensive if you dont shop around.
Depends on time vs money. If you got time K&N is decent Air Filter. If you dont want to spend the time cleaning or re-using get throw away Air Filter.
I was looking into the reusable Oil Filter. VERY VERY Expensive for initial investment that wont pay off for a long time...
