The CSF B58 Thermal Rejection Competition Spacer is an intake-manifold spacer engineered for use with the CSF B58 Super Manifold. Made from patented KIYLEX polymer, it acts as a thermal barrier to reduce conductive heat transfer between cylinder head and manifold, lowering intake air temperatures and combating heat soak. It installs without gaskets, includes hardware, and targets motorsport applications where managing IATs is critical.
