Cometic Toyota 3K/4K 84mm Bore .043 inch Copper Head Gasket

This Cometic head gasket is made from a full dead soft copper material, measuring .043 inches thick with an 84mm bore. It's specifically designed for Toyota 3K and 4K engines that have already been machined to accept steel O-rings for handling extreme cylinder pressures. Copper is a popular choice for these applications because it compresses easily during installation, creating a solid seal.

If your engine has been prepared for steel O-rings, this gasket is a well-built option to ensure a reliable seal between your cylinder head and engine block. The dead soft copper material conforms well to the surfaces, especially when the engine block and head have been machined for the O-rings.
