1967 Mopar 426 Hemi 2x4 RO/WO Air Cleaner with Seal NOS. This is an NOS original air cleaner base with seal for the specialty 67 factory race cars featuring the 426 street hemi. This piece is specific to the 55 each produced of the RO/GTX and WO/Coronet R/T cars that were specially prepared for super stock drag racing (i.e. factory lightweights).


This assembly is in excellent NOS condition and will enhance your restoration. Best of all, it is a very rare and genuine NOS Mopar part.


For further information on the restoration process, please contact us directly.




This assembly is correct for the following 1967 Super Stock models featuring the 426 hemi 2x4 barrel engines:


Coronet R/T WO Code 


Belvedere GTX RO Code

This assembly will fit a myriad of A/B/C bodies with the 426 2x4 inlets, but is only correct for the 67 RO/WO cars. 

Note: the base is specific to the hemi engines featuring twin Carter AFB carburetors with a 4 1/8" flange. It will not fit the more modern carburetors (Holley/Edelbrock, etc...using the 5 1/8" iterations -including the Edelbrock AFB).   




The assembly will fit factory Carter AFB twin 4 barrel carburetors with a 4 1/8" diameter flange - it will NOT fit  Holley, Carter, and Edelbrock variations with the 5 1/8" carburetor flange. If you have modified your carburetor or intake manifold, please inquire first prior to bidding to ensure fitment is correct. Return requests for non-fitment will not be honored.





The assembly will ship within one day (usually the day of payment) with shipping/tracking information provided.
