Opinion:
Paper filters dirt better than foam and oil.
Foam flows more air.
So with foam the computer could adjust fuel/air ratio to add more fuel thereby increase power. Maybe 1 to 5 HP which would not be felt seat of the pants.
Foam will make the intake sound "roar" louder and perhaps more attractive to the driver.
Foam oil, be careful not to over oil as this can effect the MAF/ wire in the throttle body.
Paper works well as is.
If in a dusty environment this is the best option.
Not sure of the cost difference. I believe maintenance schedule is to replace paper filters ever 50K mileage....you have to confirm and see if one offers a cost benefit for you.
