Take your B58 setup to the next level with the CSF A90 Supra / BMW B58 Thermal Rejection Competition Charge-Air Manifold Spacer. This little piece makes a huge difference. By insulating the manifold from heat coming off the cylinder head, it keeps intake air temps lower, reduces heat soak, and lets your turbo breathe cleaner, cooler, and harder. On the track, in drag lanes, or during spirited street runs, your car will respond sharper, spool faster, and hold boost longer without compromise.

Engineered with precision, the Thermal Rejection Spacer is made from KIYLEX, a revolutionary polymer as strong as aluminum and resistant to temperatures up to 1100 degrees Fahrenheit. Tested on A90 Supra builds by Visconti Tuning, this spacer proves its worth in real-world conditions, helping to shave off manifold temperatures and improve charge-air cooler efficiency. It slots perfectly under the CSF B58 Super Manifold to give you measurable performance gains with no fuss.

Precision Engineered Design

Made from KIYLEX, a patented high-performance polymer. Spacer height is 6.5mm to optimize thermal separation. Acts as a thermal barrier that dissipates heat between cylinder head and intake manifold. Self-sealing design eliminates need for gaskets or sealants. Designed specifically for use with CSF #8200 B58 Super Manifold.

Configuration Options

Compatible only with CSF B58 Super Manifold. No other manifold configurations are supported. Perfect for drag, roll-racing, or high-demand motorsports applications.
