# CSF B58 Thermal Rejection Competition Spacer (For Super Manifold 8200)

The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX, a patented revolutionary high-performance final stage polymer. KIYLEX is as strong as aluminum and can withstand temperatures up to 1100'F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX Intake Manifold Spacer for the B58 Motor.
