CSF 7058
This aluminum radiator is an OE replacement that cools better than stock, and lasts much longer. CSF radiators have a 42mm thick dual row core with more a more efficient fin design to keep your coolant temps low even in hot weather and heavy use. The triple pass design of this radiator means the coolant passes through it 3 times before returning to the engine, allowing the most cooling possible.
This radiator fits E46 M3 only.
