The Racing Lab Front Intercooler Radiator is a high-performance cooling upgrade designed for BMW G-Series (B58) and Toyota GR Supra A90/A91 platforms. Engineered for high-load and track conditions, it delivers improved thermal control and consistent performance under sustained boost.

Compared to the factory cooling system, this upgraded radiator features a larger core design with approximately 30% increased cooling capacity, allowing for more efficient heat dissipation.

Based on real-world datalog testing (ambient temperature: 28°C, BM3 Stage 2), the Racing Lab system demonstrated a significant reduction in intake air temperature:

• OEM peak IAT: 69.0°C
• Racing Lab peak IAT: 54.5°C
• Up to ~14.5°C reduction under load

This improvement helps reduce heat soak, maintain stable power output, and improve consistency across multiple laps.

Constructed from full aluminium with a high-efficiency core design, it offers increased durability and reliable performance for both street and track use. Designed as a direct replacement, it installs seamlessly with factory mounting points.
