I noticed that K&N's are recommended for increased performance. Saw a review that someone had an increase of 5-10mpg between fill ups from changing to a K&N using a 99' Road King . I read off AMS oil's website that better oil flow through a filter increases efficiency. Better efficiency often leads to less work meaning less fuel and or more power. Just wanted to see if anyone else noticed a difference if they had switched from stock filters.

(Even those crappy Fram filters that I ran for the first 90,000 didn't hurt anything either.)
OEM just means Contract given to the lowest bidder. And currently that's Champion Labs ( who will sell you a filter directly too.)

Oil filter(s) have minuscule effect on MPG...probably non-measurable so if you're looking for better mileage - tile for some performance changes w/your 2013. Adding things like free-flowing a/c (Stage-1) + less restrictive exhaust (CAT-less) and tuner will be great enhancements for increasing riding comfort & distance. Do some research on air, exhaust & tuners & you'll find lots of great combinations available. Good luck!
BTW, I stick w/HD filters...probably one of the only things not a "hundred dollars" in the store and works same as most + readily available.
