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

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

Reduce Intake Air Temperatures. Combat Heat Soak. Maximize Performance.

Unlock peak efficiency from your CSF B58 Super Manifold with the CSF Thermal Rejection Competition Spacer, the ultimate thermal management upgrade for high-performance and motorsport applications. Constructed from KIYLEX™, a revolutionary polymer as strong as aluminum and capable of withstanding temps up to 1100°F, this spacer acts as a critical thermal barrier between the cylinder head and intake manifold—reducing heat transfer, lowering Intake Air Temperatures (IATs), and improving overall performance consistency.

✅ Key Benefits:

• Made from KIYLEX™ – Aerospace-grade polymer that resists heat and conducts less than aluminum

• Reduces Manifold Heat Soak – Limits heat transfer from the head to the manifold

• Lowers IATs for Maximum Power Output

• Improves Efficiency of Charge-Air Cooling System

• Designed for Drag and Roll-Race Conditions – Keeps IATs consistent between multiple runs

• Perfect Complement to CSF B58 Super Manifold (#8200)

• Exclusive CSF Partnership – CSF is the official distributor of KIYLEX spacers for the B58 platform

🏁 Built for Motorsport, Beneficial for Street

While engineered for drag racing and roll-racing, where prolonged idling causes serious heat soak issues, this spacer also offers substantial benefits for daily-driven, tuned, or track-focused B58 vehicles. Its ability to lower heat transfer between the aluminum manifold and cylinder head helps stabilize performance across a wide range of operating conditions.
