Performance Radiator for the BMW E46 Non M Track Day Customer. Built by PWR in Australia using race proven 55mm core and aircraft quality aluminum resolves the problematic plastic tank radiator. Capable of handling high horsepower, track day events. Perfect for forced induction. Will not accept stock fan shroud. A Spal fan should be used instead. A major upgrade that looks great under the hood and will keep your E46 cool in any situation.
