1971-1972 GTO & Formula ram air cleaner ID
I have three ram air cleaners off of 1971 - 1972 A-body and 70 - 74 Formula cars. All three have minor variations in construction. I'm trying to determine what application each of these fits. I know one is 455HO because it has a hot air tube on the passenger side, but I'm not sure what year. I'm also not sure of what the other two are. I suspect one could be bought over the counter.
See the photos. Air cleaners from left (1) to right (3) Differences: Air Cleaner 1 D-port (left) - 4 wire/vacuum hose clips on bottom - One flat at back - Flat straps on dashpots Air Cleaner 2 455HO (middle) - 2 wire/vacuum hose clips on bottom - Two flats at rear - Curved dash pot straps Air Cleaner 3 D-port (right) - 3 clips, appear to be dual (different from other air cleaners) - One flat at rear - Flat straps on dash pot Last edited by poncho-mike; 01-17-2026 at 12:20 PM. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
