I switched the original air cleaner on my M35 to a K&N lifetime filter. I have three new air elements that I no longer need (Universal Part #301049), along with the filter assembly itself. I'm looking at $30 for the three unused air elements, the filter assembly is free if you're looking for a spare. Postage is extra. Contact me at abelovarac1263@gmail.com if interested. I only get on this site occasionally so you'll get a quicker response by emailing me directly.
