Product Description

The CSF High-Performance Triple Pass All-Aluminium Radiator is a premium cooling upgrade for the BMW E9X M3, designed to improve cooling efficiency for high-performance road driving, track use and high-horsepower builds.

Built with CSF’s advanced B-Tube Technology, this radiator uses a 2-row 42mm core with specially engineered “B” shaped tubes to increase heat transfer surface area by approximately 15% compared with conventional tubes. This helps improve coolant flow and overall thermal efficiency.

The triple-pass flow structure forces coolant to travel across the core three times before exiting, helping achieve lower outlet temperatures and more stable engine cooling under sustained load.

With an ultra-efficient multi-louvered fin design, CNC-machined brackets and fittings, an all-aluminium race-style drain plug and a smooth satin finish, this radiator combines performance, durability and direct-fit installation for the S65-powered E9X M3.
