Pierce Manifolds Dual Air Filter Plenum – 5 1/8 Inch – Cast Aluminum – Holley, Edelbrock, Rochester

This is the Pierce Manifolds cast aluminum dual air filter plenum, sized at 5 1/8 inches.

It's built to work with Holley, Edelbrock, and Rochester carbs—basically the usual suspects.

Brand new, part number PM3796.

No UPC needed, but California buyers should note the Prop 65 warning.

If you're building a dual inlet setup and want something that looks clean and flows hard, this plenum is it.

No plastic, no fluff—just machined aluminum ready to bolt on.
