CSF's Thermal Rejection Competition Spacer is a follow-up upgrade for cars already running CSF's B58 Super Manifold. It installs between the manifold and the cylinder head to cut conductive heat transfer between the two, which lowers manifold and intake air temperatures, improves charge air cooler efficiency, and reduces heat soak between runs. It's built from KIYLEX, a high-performance polymer CSF rates as strong as aluminum and capable of handling temperatures up to 1100 degrees Fahrenheit, aimed at drag and roll-racing setups where the car sits idling in staging lanes between passes and heat soaks the manifold. Important Compatibility Information This spacer requires CSF's B58 Super Manifold to already be installed. It does not work with the factory OEM manifold or other aftermarket manifolds. Features KIYLEX high-performance polymer construction, rated to 1100 degrees Fahrenheit Insulates the manifold from cylinder head heat transfer 6.5mm spacer height Self-sealing design, no gaskets or sealants required Reduces heat soak in staging-lane and stop-and-go conditions What's Included Thermal Rejection Competition Spacer Installation Hardware Product Specifications SKU: C00B 8200S MPN: 8200S Manufacturer: CSF Fits BMW B58-equipped G-series models and the Toyota GR Supra (A90/A91) running CSF's Super Manifold (#8200) Need the Super Manifold Too? This spacer only works with CSF's B58 Super Manifold, sold separately. Frequently Asked Questions Will this work with my stock manifold?No, it is designed specifically to pair with CSF's own B58 Super Manifold and will not work with the factory manifold. Do I need any gaskets or sealant to install it?No, the spacer is self-sealing and does not require gaskets, silicone, or other sealing agents. What temperature can this spacer handle?CSF rates the KIYLEX material up to 1100 degrees Fahrenheit.
