CSF High Performance Auxiliary Radiator BMW F8X M4 M3 M2C
Product Description
The CSF High-Performance Auxiliary Radiator is a cooling upgrade for selected BMW F8X M3, M4, M2 Competition and M2 CS models, designed to outperform the factory auxiliary radiator under demanding road, track and high-power conditions.
Built to improve cooling efficiency and durability, this CSF auxiliary radiator features a larger 2-row 42mm core, an approximate 7% increase in core size and a 10% increase in tank volume compared with the OEM unit.
CSF’s exclusive B-Tube Technology, combined with 6.5mm tall multi-louvered fins, helps maximise surface area contact and heat dissipation, supporting more stable cooling performance during sustained high-load driving.
With 100% TIG-welded aluminium construction, OEM-style quick-connect inlets and outlets, detachable stone guards and an OEM+ satin black finish, this radiator is designed as a true drop-in upgrade with no modifications required.

Warranty & Disclaimer
Warranty
Most products include a manufacturer’s warranty covering manufacturing defects only. Warranties do not cover wear and tear, improper installation, misuse or neglect, track use, competition or racing environments, labour costs, vehicle damage, downtime, or consequential loss. Warranty outcomes are determined by the manufacturer, not Clubsport Garage. Items must be returned for inspection at the customer’s cost unless agreed otherwise.
Fitment & Installation
Many products are aftermarket components and may require professional installation or minor adjustment. Perfect OEM-level fitment cannot be guaranteed. Professional installation by an experienced workshop is strongly recommended. Installed or used items cannot be returned.
Motorsport Use Disclaimer
Some products are intended for off-road, track, or motorsport use only and may not be legal for road use, for example non-TÜV/DOT-approved parts. It is the customer’s responsibility to ensure compliance with local laws, insurance requirements, and vehicle regulations. By purchasing and installing aftermarket parts, you accept all responsibility for ensuring compatibility, legal compliance, proper installation, and any resulting wear, damage, or failure.
