While doing service I found my air filter quite dirty so want to replace it with stock. I am sure I could get one from my "Local" HD dealer, but they are 1.5 hr round trip and I really do not like them much (long story). Everything I come up with on line is like a K&N or Screaming Eagle. replacement..and I just can't spend the x-tra cash right now for an upgrade. Does anyone know an online source for stock OEM air filters for a 2001 Road King?
