do88 BMW M3 (E90/E92/E93) Front Mount Radiator

Ever since the first E30, the BMW M3 has enchanted enthusiasts around the world, and the E90 generation is no exception, widely considered the perfect combination of usability and performance. With its well-balanced chassis, thorough construction, and hefty S65 V8, it's almost the perfect base for a race car. But only almost, ascending coolant temperatures are one of the platform's few known issues. do88 analysed the reasons behind this and developed a genuine solution.

The result is a 14% larger core volume than the factory unit (11,193cm³ versus 9,795cm³) and, in real-world testing, an 8% lower coolant temperature (73°C versus 79°C stock). A triple-pass flow design routes coolant across the core three times before it exits, maximising contact time with the cooling fins for the lowest achievable outlet temperature. Developed and extensively tested in conjunction with a German racing team, this radiator is ideal for both the clubman racer and track day enthusiast wanting maximum performance from their M3 while protecting the engine from overheating.

Works with: OEM mounting points and hose connections. Genuine drop-in fit, no modifications necessary.
