    Not really sure as I don’t have a mini Mac/intake to look at ... I can tell you for certain that they work fabulously on the 3 models noted ...

    The manual says replace filter every 10.000 killowatts used.

    FYI......... over the years, the motorcycle guys have pretty much stopped using these oiled cleanable filters. Lots of scientific-ish studies done by very smart guys with flow meters and filtration testers showing that they do not filter well at all when new, and once dirty restrict flow very quickly.

    No idea how that relates to saw filters but figure I’d throw it out there

    You are correct, I never wanted a K&N filter on anything. Some guys swear by em, but not me.

    Yah , here is a picture of the stock hd2 filter off my 362c after 2 hours of use ,you can CLEARLY see fines ! you can Clean the filter by stopping the machine , removing the cover , and twisting the filter off ... then tap tap tap and reinstall , now some guys will say “ well you blow them out with compressed - air “ yeah that’s a great idear IF you are at home ... never seen a tree with an air line attached lol ! Also the plastic “twist lock system” that holds the filter tight is a known commodity...after repeated twist off ,twist on over and over the seal integrity is compromised ... STIHL reccomends replacing filters at monthly intervals at $42/ filter in the manual ... I only have about 6 hrs of testing so far ; in that time I have not needed to stop and “clean” anything ! Also NO FINES in the velocity stack or the carb throat ... Now it may be that I am meticulous in keeping a sharp chain and also the fact that the filter is drawing from the rear of the Saw (bypassing the air injection system ) - also the species of timber That I cut gives nice chips rather than powder ... your mileage may vary ! The most important aspect is the performance!!! ... when you remove the stock baffle and filter and install The kit you realize noticeable gains in throttle-response and power ... I’ve gotten between an 10-15% increase in cutting speed simply by removing the stock filter / baffle and replacing with the kit depending on which model ... these are substantial gains that when combined with correct port work can give you 50% or more wood cut in the same time .... the only drawback is that the cover must be cut to accommodate the filter ... I’ll continue to test but right now it appears to be a winner ... the pic of the filter is above

    It's the money you have to pay after the police give you a ticket.
