CSF 8200S High-Temp Gasket for B58

The CSF Thermal Rejection Spacer is the next-level upgrade for the B58 Super Manifold (CSF #8200). Manufactured from KIYLEX, a patented, revolutionary, next-generation high-performance polymer. KIYLEX is as strong as aluminum and can withstand temperatures up to 1100°F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier lowers manifold temperatures, which helps reduce Intake Air Temperatures (IATs), improve intercooler efficiency, and combat heat soak. CSF is the exclusive distributor of the KIYLEX intake manifold spacer for the B58 engine. Adding a thermal spacer is especially beneficial for drag racing applications where cars typically sit between runs. This causes the liquid-to-air manifold to heat up significantly as airflow is not passing through the front-mount intercooler (responsible for cooling the charge air coolant running through the manifold) while the car is idling. This results in initial IATs on subsequent runs being higher than on the first run. The B58 Super Manifold is constructed from Billet Aluminum and is 100% Tig Welded for strength, allowing it to withstand higher boost pressures compared to the OEM plastic manifold. Aluminum has a higher thermal conductivity than plastic, resulting in a higher rate of heat transfer between the cylinder head and the manifold. Adding the Thermal Rejection Spacer reduces heat transfer between the two metal components (cylinder head and manifold). The spacer absorbs heat from the cylinder head and dissipates it rather than transferring it to the manifold. The Thermal Rejection Competition Spacer was designed for motorsport competition vehicles that require the absolute best cooling to gain a competitive edge. With all that said, installing this spacer on any vehicle equipped with the CSF B58 Super Manifold offers significant benefits.
