Further Information
The CSF B58 Thermal Rejection Competition Spacer is a precision thermal barrier designed to insulate your intake manifold from conductive heat transfer. By reducing manifold temperatures and lowering Intake Air Temperatures (IATs), this spacer improves charge air cooler efficiency and combats heat soak—especially critical during drag racing and roll-racing events where extended idle time causes extreme thermal buildup.
Key Features:
- Manufactured from KIYLEX, a revolutionary high-performance polymer as strong as aluminum
- Withstands temperatures up to 1100°F with proven 15% reduction in manifold temperatures
- Self-sealing design eliminates need for gaskets or sealing agents
- 6.5mm spacer height acts as thermal barrier between cylinder head and manifold
- Tested and validated on competition vehicles by Visconti Tuning
- Compatible with CSF B58 Super Manifold for optimal thermal management
Includes:
- Thermal Rejection Spacer
- Installation hardware and instructions
- Limited Lifetime Warranty
Lower IATs. Better cooling. Competitive edge. Built for B58 performance.
