To chime back in, the replacement I put in there was a Bosch unit I bought at Autozone for around $18. It's pretty flimsy compared to an engine air filter--I mashed it in a few times while getting it back in there, had to kind of fold it back straight. It'll be hard to tell the difference for a few days--my customary oil drippings on the exhaust manifold have to burn off first! Funnels? Who needs 'em!!!
