Hey guys, A new air filter for my Universal M4-30 cost $17 and which seems expensive for a simple ring of foam rubber sown like a bracelet. I removed the old oil caked foam from the little screen and cleaned it up with solvent before installing the new one and had to flatten the venturi to get a good fit. The parts guy said it was more of a silencer than a filter. Anybody know of a better air filter for a diesel engine like mine?
