The CS11-4×4 header works with virtually all engine swap kits.

WARNING: The vehicle’s steering shaft will run between the engine block and header on this application. Solid motor mounts, engine plates, or the installation of a torque limiter are strongly recommended to prevent the engine from shifting, which may cause the steering shaft to bind.

FINISH:

Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high quality standards, we apply a multi-layer inside and outside aluminized ceramic coating in-house and then polish the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases and increases the longevity of your header investment.
