Good catch Ferret, my bad for skimming through a little toooo fast. I think I would stay with OEM for the air filter too, but that is just me.
K&N has excellent flow, but filters better when a bit dirty (less flow).
I had a K&N on my first Sportster, but I think most of the gain was from more air flow around the ham can with a Screamin' Eagle backplate. I modified the backplate on my second Sportster, using a stock air filter and had about the same gain.
Also had a K&N "cold air induction" on my 2003 Jeep Wrangler.
So, I am not anti-K&N, but would prefer to exchange air filters, rather then clean and re-oil.
The HiFlo HFA1932 was under consideration due to price. But the response from HiFlo is that they do NOT flow test. Don't know how they can claim the same flow as OEM, yet not test.
My airfilter is still looking new at over 9,000 miles.
