The CSF 7058 is an all-aluminum engine coolant radiator for the 2001–2006 BMW E46 M3. Its triple-pass layout sends coolant across the core three times before it exits, while retaining the factory radiator mounting arrangement.
A two-row, 42mm B-Tube core replaces the original radiator construction. CSF’s current specification adds 5mm Track-Spec multi-louvered fins for 2026. This is the engine radiator; an engine oil cooler serves a separate circuit.

Product FAQs
Does the CSF 7058 fit a non-M E46?
The listed application is the E46 M3 with the 3.2L engine. Do not choose this radiator for another E46 solely because the chassis generation is the same.
Can I retain the factory fan and A/C condenser?
Yes. CSF specifies compatibility with the original fan shroud, condenser, mounting brackets and quick-connect hoses.
Does this replace the M3 engine oil cooler too?
No. The radiator carries engine coolant. The oil cooler is a separate component with separate oil connections.
