I would go dry.. oiled filters cause more maf issues than it's worth

My 67 Econoline has a stock oil bath air cleaner made what Ford called "coir" - coconut husk. Don't know if it filters more than bugs out of the carburetor but it keeps the engine block and manifold and most of the frame from rusting.
At every bump, it vomits oil that the fan heaves everywhere. It drips down the sides of the block when I shut it down. When I change the oil I refill what hasn't splashed or sucked out of the coir air cleaner with the cheapest Red Dot oil I can find. I wrap the motor mounts with plastic bags to keep from being dissolved by the flung oil.
Ah, those were the days.

You should see the ones on a 8v71 Detroit Diesel MCI bus!! Metal weave stuff with oil bath that's about 15 inches diameter.
They work though, and when they get dirty and restricted, you can tell a world of difference after you clean it. It feels like you got twice the power back.
That meaning as you keep pedal slammed to floor, it gets to same speed in half the time.
Not really that bad and I do miss driving the 40 ft, 4 speed manual spicer from time to time.
It was fun!!

Dry. It keeps the MAF and throttle body cleaner.

FWIW
We've run oiled air filters for 40 years in my bikes.....no big deal and I've run an oiled K&N in my SLK for the past 180,000 miles....just oil properly but most Over-oil causing issues....this is one of those cases where "more" is bad, very bad!
The bikes are all old tech...no sensors, carbs etc. The '02 car has a complete Canbus system complete with all the sensors, maf, FI etc...also no issues....JMHO

I just switched out the oiled K&N pod filter in the K&N FIPK air box in my S2000 for an AEM dry filter. Just 'cuz as the K&N has shown no problem for the past 5 years. I run the Ford OE filter in my '17 Expedition.
Plenty of testing shows some of these aftermarket filters provide better air flow.
When the tests are carried beyond that they show the acceleration gains are real but too small to be felt by the driver. Do we have a charcoal element in our air cleaners?
