Auxiliary GT4 Right Radiator, C&R - F8X M2/M3/M4

C&R (PWR) aluminum auxiliary radiator can be used on standard F87 M2 Competition, F80 M3, F82 M4, and M4 GTS models for a bolt-in upgrade. A matching PWR radiator was used on M4 GT4 and M2 CSR models on the left side.

This is an all aluminum tube-and-fin auxiliary radiator upgrade for F87 M2 Competition, F80 M3, F82 M4, and M4 GTS. This is the small radiator located in the right (passenger's) side front bumper. This radiator works with the larger charge air cooler (17112284608) in the nose and circulates coolant used in the top-mount intercooler. Coolant flows from the intercooler and electric auxiliary coolant pump to this auxiliary radiator and then onto the main charge air radiator in front. Given its location it is very susceptible to rocks and debris.
 

• Handmade and professionally TIG welded in the USA
• Motorsport-engineered tube and R-fin technology for the highest heat rejection
• Direct (non-homologated) replacement for the original M4 GT4 and M2 CSR cooler
• Billet aluminum tanks
• Up to 30% increase in cooling efficiency

Homologation Note: this product may have fitments and applications listed that originally used a different part for rules compliance or homologation. We include these fitments because this part is compatible and may be an improvement or upgrade over the original part. However, as with any racing series or class, it is up to the vehicle builder or owner to ensure parts compliance with series or class rules.

BMW added this extra radiator to the left front bumper to increase cooling capacity and surface area. C&R is part of the PWR cooling group, world-famous for their expertise in cooling at the top levels of GT, Le Mans, NASCAR, and F1 racing. They used their own tube and fin core to maximize the cooling efficiency in the tight space available. The end tanks are billet machined aluminum, not cast, folded, or bonded. High precision fittings, CNC machining, and TIG welding throughout ensures the highest quality construction to prevent pressure loss, and the lowest weight, in a bolt-on replacement.
