This is a reproduction of the 426 hemi air cleaner base plate for Edelbrock or AVS carbs. The base is made out of metal just like the originals. Don’t buy the aftermarket fiberglass ones to save a buck, they don’t work! This is the big size for the AVS or Edelbrock style carbs, if you want a base for stock AFB carbs we carry those as well.
The AVS has a bigger mouth than the stock AFB’s seen stock on a Hemi. This is for the bigger carbs.
