SpeedFactory Copper Exhaust Manifold Gasket for B Series

SpeedFactory Copper Exhaust Manifold Gasket for Honda B-Series Engines

The SpeedFactory Copper Exhaust Manifold Gasket is the ultimate sealing solution for your high-performance Honda B-Series engine. Designed to withstand the extreme heat and pressure of racing and turbocharged applications, this gasket delivers the reliability and performance your setup demands. Whether you're running a high-compression street build or a fully boosted drag setup, SpeedFactory’s precision-fit copper gasket ensures maximum durability and consistent sealing under the harshest conditions.

Constructed from .039" thick (1.0mm) solid copper, this gasket provides exceptional thermal conductivity and superior sealing properties. The .061" (1.55mm) embossed sealing rings around each exhaust port conform to irregular surfaces and increase clamp load, creating a total thickness of .100" (2.55mm) where it matters most. Unlike conventional fiber gaskets, the SpeedFactory Copper Exhaust Manifold Gasket won’t blow out, break down, or deteriorate over time—making it ideal for high-performance street, drag racing, and turbocharged applications.
