CSF Thermal Rejection Manifold Spacer – BMW (G-Chassis, B58 Gen 2)

OVERVIEW

The CSF #8200S Thermal Rejection Competition Charge-Air Manifold Spacer is an upgrade for the CSF Gen 2 B58 "Super Manifold" (#8200) on the Gen 2 B58 BMW G-chassis models. It sits between the cylinder head and the intake manifold and acts as a thermal barrier, reducing heat transfer into the manifold to lower manifold temperatures, intake air temperatures and heat soak, and to improve charge-air cooler efficiency.

The spacer is machined from KIYLEX, a patented high-performance polymer that CSF states is as strong as aluminum. CSF highlights it for drag and roll racing, where cars idle in staging lanes with little airflow over the front-mount heat exchanger and starting IATs climb on later runs. It is self-sealing, so no gaskets, silicone or sealants are needed.

SPECS

• Material: KIYLEX high-performance polymer, rated to approximately 1100°F
• Spacer height: 6.5mm
• Thermal barrier between the cylinder head and the intake manifold

• Self-sealing — no gaskets, silicone or sealants required
• Compatible with the CSF #8200 Gen 2 B58 Super Manifold only; does not work with the OEM manifold
• Limited lifetime warranty to the original purchaser
