The topic today is Tri-Power Air Cleaners, Holley Air Cleaners and even a link for Rochester Tri-Power Air Cleaners.
O'Brian Truckers is located in Charlton, Massachusetts and makes a really nice set of Air Cleaners for the Holley and Rochester Tri-Power Carburetor systems.
Several Links, just click on them and see what is available. I do not believe that this info in any way would affect Ames Performance sales.

The Mopar/ GM Air Cleaners are 'rounded corner' "D" shaped on the Air Cleaner Retention Ring.
The Ford Air Cleaners are 'sharp corner' "D" shaped on the Air Cleaner Retention Ring.
I own 3 sets of the air cleaners. 2 sets for the Holley Systems I have and one set of air cleaners for the modded 4412 500 cfm 2 bbl carbs I built up.
