Base Gasket – 4500 Non Stick (Large Open 5.300)

Base Gasket (Large Open) 4500 gaskets are a great way to ensure a leak free seal. Gaskets are made in-house by APD using the same corrosion resistant, anti-stick MP15 material that we use in our carburetors and fuel systems.

*Larger opening than standard open gaskets, and are used on intakes with opened top flange.
