Uprated 42 mm Alloy Radiator for BMW E46 M3 by PWR
Keep your S54 running cool with this high capacity PWR alloy rad, engineered as a straight swap for the factory unit on BMW 3 Series E46 M3 models from 2000 to 2006. Hand built in Australia and designed for demanding fast road, track day and drift use, the rolled dimple tube and optimised louvre fin core delivers rapid heat rejection and dependable temperature control in all conditions.

Whether your original radiator is tired or you are chasing reliable cooling for spirited driving, time attack or drift, this uprated heat exchanger keeps temperatures steady in traffic and under flat out lapping. It is a bolt in replacement that works with factory size hoses to make installation straightforward while delivering race ready cooling performance.
We run this PWR 42 mm core on our own E46 M3 projects and have fitted it to many customer cars. Feedback has been consistently excellent, with quicker cool down, rock steady gauges during hard sessions and added peace of mind for daily and weekend use.
