The only thing wrong with oil bath filters is that in modern times people are not prepared to do the service work to keep them clean. How many tractors have you ever seen with dusted engines and a functioning air cleaner?

As a kid I spent many happy hours cleaning the dirt out of the oil bath on our tractor and washing it in petrol, but the dirt all stayed in the bowl and didnt make it into the engine.

The rant is fine
Maybe back it up now with oil analysis

When I was a teenager I had a beetle with a cool oil bath air filter. Always worked fine and minimal maintenance really.

Oil Bath air cleaners are better than a K&N for sure, but have the same problem that they would oil the MAF on a new engine. Also, along with the oil mist they create, you have a much greater potential to re-aerosolize the dust you have collected (compared to a fibrous filter).

Wasting your time Ben. After all, it's not like you ever drive offroad is it?

At least if the paper filter is geting durty it is doing its job. Years ago when i was a service manager for worked for Leyland & we had to do an engine rebuild we would get Repco in to measure everything , the guy doing the measureing would take one look at the head & pistons on some motors & say sports filter & then when we looked in the box of bits that had been removed to get the motor out we would find the vehicle had foam sports filters . We always found the motors with sports filters required more machining than the ones with paper filters . The best were the paper filters with the oiled foam fited around the out side. & oil barth filters are the best filters any way.

Race cars as well Rick... I was reliably installed that the 2 MM F1 engine failures in Bahrain (2004???) were due to sand particles from the track bouncing through the K&N...
