Performance Radiator for the BMW E36 and late E30 6 Cylinder (not for E30 auto trans) . Built by PWR in Australia using race proven 42mm core and aircraft quality aluminum resolves the problematic plastic tank radiator. Capable of handling high horsepower, track day events as well as daily drivers. Great choice for S50/S52 engine swaps. 42mm core will fit in a E30 better than the 55mm because it is thinner but don’t be fooled by the thinner core, it will outperform all other manaufactures applications. Accepts stock fan shroud and hoses. Uses upper and factory bushings and upper clips and factory aux fan temp sender for a true bolt in application. A major upgrade that looks great under the hood and will keep your engine cool in any situation.
