The CSF B58 Thermal Rejection Competition Spacer is the ultimate upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX?, a revolutionary high-performance final stage polymer, this spacer is as strong as aluminum and can withstand temperatures up to 1100?F. Designed to insulate the intake manifold from conductive heat transfer from the cylinder head, this thermal barrier reduces manifold temperatures, lowers Intake Air Temperatures (IATs), improves charge air cooler efficiency, and combats heat soak.
The addition of the Thermal Rejection Spacer is especially beneficial for Drag/Roll-Racing Events where vehicles sit in staging lanes in-between racing, causing extreme heat soak to the liquid-to-air manifold. The B58 Super Manifold is made from Billet Aluminum and 100% Tig Welded for strength, allowing it to withstand higher boost pressures compared to the OEM plastic manifold. However, aluminum has higher thermal conductivity than plastic, resulting in a higher rate of heat transfer between the cylinder head and manifold. Adding the Thermal Rejection Spacer reduces heat transfer between the two metal components, absorbing heat from the cylinder head and dissipating it rather than transferring it to the manifold.
The Thermal Rejection Competition Spacer is designed for vehicles competing in motorsports who demand the best cooling for a competitive edge. It offers significant advantages when added to any vehicle with the CSF B58 Super Manifold installed. The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold, providing improved efficiency and combating heat soak.
The CSF #8200S Cooling product is designed to be a "Drop-In Fit" application, installing in the OEM location with no modifications necessary. Please refer to the manufacturer repair manual for standard installation instructions. If you are not confident in installing this product, CSF recommends taking it to a qualified installation facility.
