I think its easy to see how engine builders feel.

ALL production cars, motorcycles, dirt bikes, lawn mowers, generators have been shipping with air filters for over 50 years and its not because the manufactures want to spend extra money.

I also think most model A engine builders insist you run an air filter or it voids the warranty.

Unfortunatrly this discussion gets repeated almost as often as oil arguments .
