It absolutely does have an anti-drainback valve.
It just so happens to be orange in the K&N.
It absolutely does have an anti-drainback valve.Per the K&N SS-2010 Website, this unit does not have an "Anti Drain-Back" Valve (the black rubber valve visible under the small holes surrounding the one big mounting hole) which Factory Units do have and is GOOD to have so the oil does not drain out of the oil galleries and back to the crankcase after engine shutdown.
I also could not find anywhere what the "Micron" Filter Rating is for this unit which is important to know.
For me, NOPE!
You're using the right lube but you should also use the filter 90% 20 micronsIt absolutely does have an anti-drainback valve.

I don't have to call I use the best filter out there.just saying from what I heard from a review of different oil filters thats why I said I believe its 10 microns though not 100 percent sure you gotta call K&N to find out.
OP is a D-bag for deleting his posts. I addressed the potential misconception of a missing anti-drainback valve applied to the 2010 filter.The OP wasn’t asking about the normal KN oil filter. The thread was about the reusable one.
