Quick Q, for those with a Gruppe M, what do you use to clean the filter? And how do you take it apart to clean all the important bits?
Just do it as you swap your mmr wilks said:How often would this need cleaning :?

When I asked Gruppe-M in 2016, they gave me the K&N part number for the filter (RF-3301A) and said I could order it from a K&N reseller (MStyle they suggested at the time).Argenta said:Just bought one, 2nd hand (serial nr 007)
What size is the filter?
4"..?
Thinking of just getting a new (dry) one.
