CSF KIYLEX Thermal Rejection Competition Spacer (8200S) for B58 Super Manifold #8200 - Select BMW, Toyota, & INEOS 2018-2026

Fits select 2018-2026 BMW (5/7/8 Series, M240i, M340i, M440i, X-Series, Z4), Toyota GR Supra, and INEOS Grenadier/Quartermaster (B58 Engine).

The CSF 8200S Thermal Rejection Competition Spacer is a precision-engineered 6.5mm thermal barrier designed exclusively for the B58 Super Manifold (CSF #8200). Manufactured from KIYLEX, a patented high-performance final-stage polymer, this spacer provides a critical thermal break between the cylinder head and the intake manifold. By blocking conductive heat transfer, it reduces manifold temperatures by up to 15%, significantly lowering Intake Air Temperatures (IATs) and combating heat soak during high-performance driving or competition use.

Engineered for professional-grade installation, the KIYLEX material is as strong as aluminum yet offers superior insulating properties with a temperature threshold of up to 1100°F. The spacer is self-sealing, eliminating the need for OEM gaskets, liquid sealants, or RTV. This kit includes all necessary installation hardware and instructions for a seamless bolt-on upgrade to your existing CSF Super Manifold.
