BMW S55 Low-Temperature Intercooler Water Radiator Upgrade - FMCCRAD6

Keep charge temps under control and power consistent with this uprated Forge Motorsport auxiliary cooler for the S55 platform. Designed to increase heat rejection and coolant volume in the charge water circuit, it is a proven solution for fast road, track days and remapped cars where stability and repeatability matter.

Key reasons enthusiasts choose this uprated cooler

• Large high-efficiency core - 545 x 460 x 32 mm for excellent thermal performance
• Approx 1.7 litre capacity to improve coolant mass and slow temperature rise
• OEM-style black powder coated finish for a factory look with added corrosion resistance
• True bolt-on fitment - installs on factory mounts with no cutting or trimming
• CNC-machined hose connections for precise, leak-free joints
• Integrated bleed point for easy filling and maintenance

Expect lower and more stable intake temperatures, reduced heat soak and more consistent performance during repeated pulls and extended sessions. Ideal for Stage 1 and Stage 2 software, hybrid turbo setups that retain the stock layout, or any S55 that is driven hard.

Tuned S55 friendly

Remaps push the thermal limits of the standard system. This larger low-temp intercooler radiator increases surface area and coolant capacity to keep IATs in check. Run it as a stand-alone upgrade or pair it with the Forge chargecooler and expansion tank kit - FMCC1 - for a comprehensive cooling package.
