This is the CSF Thermal Rejection Competition Spacer, and this is an upgrade for the CSF Super Manifold for the B58 platform. This component is made from KIYLEX which is a patented revolutionary high-performance final-stage polymer material that is as strong as aluminum and can withstand temperatures up tp 100°F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier will reduce manifold temperatures which helps lower the intake air temperatures, additionally, it will improve the charge air cooling efficiency while deflecting heat soak.
