CSF 8200S Thermal Rejection Competition Spacer for B58

The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX, a patented revolutionary high-performance final stage 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 reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX Intake Manifold Spacer for the B58 Motor.The addition of the Thermal Rejection Spacer is especially useful for Drag/Roll-Racing Events where vehicles typically sit in staging lanes in-between racing. This causes extreme heat soak to the liquid-to-air manifold as there is not sufficient airflow passing over the front mount heat exchanger when the car is idling (which is responsible for cooling the charge air fluid that runs through the manifold). This causes the starting IATs on subsequent runs to be higher than on the initial run.The B58 Super Manifold is made from Billet Aluminum and 100% Tig Welded for strength, which allows it to be able to withstand higher boost pressures compared to the OEM plastic manifold. 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 (cylinder head and manifold). The spacer absorbs the heat from the cylinder head and dissipates it rather than transferring it to the manifold.The Thermal Rejection Competition Spacer was designed for vehicles competing in motorsports who demand the absolute best cooling in order to gain a competitive edge. With that being said, there are significant advantages to adding this spacer upgrade to any vehicle with the CSF B58 Super Manifold installed.
