CSF Toyota A90/A91 Supra/ BMW G-Series B58 Charge-Air Cooler Manifold - Sublime Yellow Green

The CSF B58 Thermal Rejection Competition Spacer is an upgrade for the B58 Super Manifold (CSF #8200). It's made from KIYLEX, a patented high-performance polymer that's as strong as aluminum and can withstand temperatures up to 1100°F. This spacer acts as a thermal barrier, insulating the intake manifold from conductive heat transfer from the cylinder head. This reduces manifold temperatures, lowers Intake Air Temperatures (IATs), improves charge air cooler efficiency, and combats heat soak, especially useful in drag/roll-racing where vehicles idle in staging lanes. It is designed for use with the CSF B58 Super Manifold (CSF #8200) and will NOT work with the OEM Manifold.
