King Racing Products Restrictor Plate O-Ring Pack Carburetor

King Racing Products Restrictor Plate O-Ring Packs are replacement O-rings (also called restrictor plate seals or gaskets) for King billet aluminum micro sprint restrictor plates. The O-ring seals the restrictor plate to the cylinder head, which helps keep dirt out of the engine and keeps the intake sealed.

Key Features:

• Replacement O-rings made for King Racing Products 600 micro sprint restrictor plates
• Sold as a pack of 4 replacement O-rings
• Seals the restrictor plate to the cylinder head to help block dirt from entering the engine
• Lets you refresh a worn or damaged seal without replacing the restrictor plate
• Made by King Racing Products, a supplier of sprint car and micro sprint racing components

Replacing the O-rings when they wear keeps the restrictor plate sealing properly. Choose the pack that matches your restrictor plate and engine style.
