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

Take your B58 Super Manifold to the next level with the CSF Thermal Rejection Competition Spacer. Made from KIYLEX, a patented revolutionary high-performance final stage polymer, this spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head.

This thermal barrier reduces manifold temperatures, lowers Intake Air Temperatures (IATs), improves charge air cooler efficiency, and combats heat soak. Perfect for vehicles competing in motorsports, this spacer upgrade provides a competitive edge.

  • Acts as a thermal barrier that dissipates heat between the cylinder head and intake manifold
  • Self-Sealing and does not require gaskets, silicon products, or sealing agents
  • Can withstand temperatures up to 1100°F and is as strong as aluminum
  • Proven to lower intake manifold temperatures by up to 15%
