[quote="Jonorow"]I believe ther is a K&N filter for the XR400 which is the same[/quote] Hi Jonorow, Maybe we can do a comparison to decide which is best suited for our CRMs, I'm inclined towards the HA-2584 for my CRM MK3. The dimensions seems to be the best fit with maybe some minor mods. What say ...

Can anyone advice if there is a K&N filter model available to fit on the MK3 or AR?
