CSF B58 Thermal Rejection Competition Spacer (For Super Manifold 8200)

If you're looking to get the most out of your B58 Super Manifold (CSF #8200), especially during demanding situations like drag racing or roll racing, this Thermal Rejection Competition Spacer is a smart addition. When your car sits in staging lanes, airflow over the heat exchanger drops, causing heat soak and raising intake air temperatures (IATs) for subsequent runs. This spacer acts as a thermal barrier, absorbing heat from the cylinder head and preventing it from transferring to the intake manifold.

This spacer is made from KIYLEX, a patented polymer that's as strong as aluminum and can handle temperatures up to 1100°F. By reducing heat transfer between the cylinder head and the billet aluminum manifold, it helps keep intake air temperatures lower, which improves charge air cooler efficiency. It's designed to be self-sealing, so you won't need any extra gaskets or sealants during installation. This spacer is specifically for use with the CSF B58 Super Manifold and will not work with the OEM manifold.

This part is especially beneficial for motorsports applications where every degree of cooling counts, but any vehicle equipped with the CSF B58 Super Manifold will see advantages. It comes with the necessary installation hardware and instructions.
