Vehicle Info NeededDivided Square Bore Carburetor Heat Insulator Gasket, 0.320 in. Thick
Ships Today
Lowest Price GuaranteeHeat soak into the carburetor is what causes percolation and hard hot restarts, especially on a dual-plane manifold sitting over a hot lifter valley. An insulator gasket puts a thermal break between the two. The divided center matters: it maintains the manifold's plenum separation instead of connecting the two halves, which would alter how the engine breathes.

- 0.320 in. thick nitrile rubber composite insulator.
- Square bore shape with a divided center to suit dual-plane manifolds.
- For four-barrel carburetors.
