CSF Thermal Rejection Competition Spacer

2020–2024 Toyota GR Supra B58 Engine

8200S

Overview:

The CSF Thermal Rejection Competition Spacer is a precision-engineered upgrade designed specifically for the Toyota GR Supra equipped with the B58 engine from 2020 to 2024. This advanced spacer works in conjunction with the CSF B58 Super Manifold (CSF #8200) to significantly reduce intake manifold temperatures by acting as a thermal barrier between the cylinder head and intake manifold. By minimizing heat transfer, it effectively lowers Intake Air Temperatures (IATs), improves charge air cooler efficiency, and combats heat soak during demanding driving conditions.

Ideal for enthusiasts and racers seeking enhanced thermal management and consistent engine performance, this spacer helps maintain optimal air charge density for improved throttle response and power delivery. Its drop-in fitment ensures a hassle-free upgrade without the need for modifications.

Key Features:

Engineered to deliver superior thermal insulation and durability, the CSF Thermal Rejection Competition Spacer offers the following key benefits:

• Constructed from KIYLEX, a patented high-performance polymer as strong as aluminum
• Withstands extreme temperatures up to 1100°F, ensuring reliable operation under high heat
• Acts as a thermal barrier to dissipate heat between the cylinder head and intake manifold
• Proven to reduce intake manifold temperatures by up to 15%, lowering IATs
• Improves charge air cooler efficiency and reduces heat soak for consistent performance
• Self-sealing design eliminates the need for gaskets, silicone, or sealing agents
• Drop-in fitment for the OEM location with no modifications required
• Includes all necessary installation hardware and detailed instructions
• Limited lifetime warranty for peace of mind
• Spacer height of 6.5mm optimized for thermal rejection without compromising fitment

Construction & Design:

The spacer is crafted from KIYLEX, a revolutionary final stage polymer that combines the strength of aluminum with superior thermal resistance. This patented material can endure temperatures up to 1100°F, making it ideal for high-performance applications where heat management is critical. Unlike traditional metal spacers, KIYLEX’s polymer composition provides excellent insulation properties, effectively reducing conductive heat transfer from the cylinder head to the intake manifold.

Its self-sealing design ensures a perfect fit without the need for additional gaskets or sealants, simplifying installation and enhancing reliability. The 6.5mm thickness is precisely engineered to maximize thermal rejection while maintaining OEM compatibility.

Performance & Sound

By lowering intake manifold temperatures, the CSF Thermal Rejection Competition Spacer helps maintain denser, cooler air entering the engine. This results in improved combustion efficiency and throttle response, especially under high load or track conditions where heat soak can degrade performance. While primarily focused on thermal management, the spacer contributes indirectly to consistent power delivery and engine reliability.

Installation & Fitment:

This spacer is designed as a direct drop-in replacement for the OEM intake manifold spacer location on the 2020–2024 Toyota GR Supra with the B58 engine. No modifications are necessary, and the product includes all required hardware and detailed installation instructions. CSF recommends consulting the vehicle’s manufacturer repair manual for standard installation procedures. For those unfamiliar with intake manifold work, professional installation is advised to ensure proper fitment and sealing.
