This is a set of 2 new port plugs and 1 plug tap to fit Buick Nailhead intake manifolds from 1957-1966.

Using this kit will keep your carburetor and fuel cool which will give you an additional 10-15 horsepower and also prevent hard starting due to fuel boiling in your carburetor.

These plugs can be used with 364, 401, 425 CID Buick Nailhead engines.
Intake manifold and gasket NOT included.
Plugs are made of black oxide coated steel.

We also offer intake manifold gaskets. Please click here to view the gaskets.
