Product Description

This DO88 upgraded all-aluminium radiator has been developed to significantly improve cooling performance over the factory item, making it a strong choice for performance road, track day and motorsport applications where thermal stability is critical.

With a 66% larger cell pack than OEM and a 48mm thick dual-row core, the radiator delivers a substantial 120% increase in active cooling area. This larger core capacity helps improve heat rejection under sustained load, reducing the risk of rising coolant temperatures during hard driving, hot weather or extended circuit use.

The triple-pass design further improves efficiency by forcing coolant to pass through the radiator three times before returning to the engine. This increases the time coolant spends within the core, helping maximise heat transfer and maintain more consistent operating temperatures.

Constructed entirely from aluminium with TIG-welded end tanks, the radiator is built for strength, durability and long-term reliability. Increased fluid volume also helps improve thermal stability, giving the cooling system greater capacity to manage repeated heat cycles and demanding driving conditions.

FAQs

Which vehicles does the Front Charge Intercooler Radiator BMW fit?

Confirm the exact model, engine and year against the compatibility list before ordering.

Why upgrade?

Just like the S55 in the F80 M3/M4, the B58 uses a water-to-air intercooler system - but with the intercooler integrated into the intake manifold. Unfortunately, this makes the system prone to heat soak, especially when tuned or driven hard. When intake temperatures rise, the ECU will reduce ignition timing or enter limp mode to protect the engine.

Is it a straightforward upgrade?

No cutting, trimming or permanent modifications are required. Supplied with detailed installation instructions, this is a straightforward upgrade for any B58 owner seeking enhanced reliability and performance. Includes integrated mounting points for the factory transmission cooler.

I still need more cooling?

Pair this heat exchanger with do88’s full intake manifold and charge pipe upgrades for a complete solution to airflow and intake cooling on the B58 platform.
