Product Description

The do88 Aluminum Performance Radiator is a direct-fit cooling upgrade engineered specifically for the BMW E9X M3 equipped with the high-revving S65 V8 engine. Designed as a replacement for the factory radiator, this unit significantly improves cooling efficiency through increased core volume, full aluminum construction, and optimized internal flow design.

Built for demanding street and track use, the do88 radiator addresses one of the known limitations of the E9X M3 platform: rising coolant temperatures under sustained load. By increasing heat exchange capacity and improving coolant flow through a larger, more efficient core, this radiator helps maintain more stable operating temperatures during aggressive driving, extended pulls, or track sessions.

The result is improved thermal stability, enhanced reliability, and a cooling system better suited to modified or hard-driven S65-powered cars.
