CSF B58 Thermal Rejection Competition Spacer – The Ultimate Heat Barrier

The CSF B58 Thermal Rejection Competition Spacer is the ultimate performance upgrade for the B58 Super Manifold (CSF #8200), designed to deliver superior thermal management for track and street use. Made from KIYLEX, a patented, high-performance polymer as strong as aluminium and capable of withstanding temperatures up to 1100°F, this spacer reduces heat transfer between the intake manifold and cylinder head.

By creating a thermal barrier, the CSF Thermal Rejection Spacer helps lower intake manifold temperatures by up to 15%, improving Intake Air Temperatures (IATs), enhancing charge air cooler efficiency, and mitigating heat soak. This upgrade is especially beneficial during drag and roll-racing events, where vehicles often idle in staging lanes, causing significant heat soak in the liquid-to-air manifold.

Paired with the CSF B58 Super Manifold, the spacer ensures peak performance by reducing the heat transfer caused by aluminium’s high thermal conductivity. Proven in motorsports and tested by industry leaders like Visconti Tuning, this spacer is essential for drivers seeking a competitive edge.

Key Features

• KIYLEX Construction: Revolutionary polymer as strong as aluminium, withstanding up to 1100°F.
• Thermal Barrier Design: Dissipates heat between the cylinder head and manifold, reducing temperatures by up to 15%.
• Improved IATs: Keeps intake air cooler for enhanced performance and charge air efficiency.
• Motorsports Proven: Ideal for drag racing, roll racing, and competitive events to combat heat soak.
• Self-Sealing Design: No gaskets, silicone products, or sealing agents required.
