BMW E30 M3 S14 (87-91) Mishimoto aluminium radiator

The Mishimoto radiator E30 is a full aluminium performance radiator for the BMW E30 M3 with S14 engine from 1987 to 1991. It is designed as a direct replacement for the original radiator and is the logical choice when your old radiator is clogged, leaking or simply no longer keeps up.

The S14 is a high-revving four-cylinder that produces plenty of heat on track. With a 42 mm thick two-row brazed aluminium core, TIG-welded aluminium end tanks and 36 mm connections, this radiator keeps coolant temperatures stable even during long sessions. A reliable base for an E30 M3 used for track days, drifting or club racing.
