Upgrade the cooling performance of your BMW with the AIRTEC Motorsport Auxiliary Radiator — engineered for tuned and high-performance B58, B46 and N55 applications.
Designed as a direct replacement for the factory auxiliary radiator, this upgrade increases cooling capacity and frontal surface area to help maintain lower coolant temperatures during aggressive driving, spirited street use or track sessions.
The AIRTEC radiator features a larger and thicker core compared to OEM, while still fitting neatly behind the front bumper using factory mounting points and original coolant connections — no cutting or trimming required.
Finished in durable black powder coating, this kit delivers improved cooling efficiency while maintaining OEM-style fitment and clean installation.
