Hey guys, I’m going through stuff I’m bringing to Norwalk to sell and have a rare air cleaner I’m looking for a value for. It is from a 67 326 HO, 6424505. It needs restored but from my research this is a rare piece as not many 67 HOs were sold.
Any help is appreciated

Please post some pics of it, never seen one. Is it a single snorkel or open element like the GTO HO air cleaner? I'm very interested in purchasing an original open element GTO HO filter. Had a want ad up here forever.

Single snorkel with an oval intake tube. Not sure I have any pics but here’s one from the internet. This is correct for an AFB 4 bbl where the GTO used the open element for a Qjet

Part number 6424505 was use on all 1967 Pontiac 400 4 bbl's with AIR and 326 4bbl's with AIR. Not that rare.

A VHTF part can be rare, but also had a limited market and doesn't make it too valuable. I gladly paid $100 for the correct 1966 326 HO Breather a few years ago.


Here's an outstanding 1967 Lemans with 326 HO that I was able to view at a local event last week. Car was in amazing condition.

I didn’t know it was for a CA emissions car nor did I know big cars used it with AIR. I thought it was only A/F body cars.
Thanks

That is directly from a 1969 Pontiac parts manual. I believe the only difference between AIR and non AIR is a square hole in the side where the hose from valve cover attaches the breather filter inside the filter housing.
