CSF Aluminum Racing Radiator - Subaru WRX / STI Manual (2002-2007)

CSF 3076 - CSF Aluminum Racing Radiator - Subaru WRX / STI Manual (2002-2007)

Upgrade the cooling system in your manual-transmission 2002–2007 Subaru WRX or STI with the CSF 3076 Aluminum Racing Radiator. Designed as a direct-fit replacement, this high-performance radiator combines durable all-aluminum construction with CSF’s efficient B-Tube technology to improve heat transfer and provide reliable cooling during spirited street driving, track use, and demanding conditions.

Precision TIG-welded aluminum end tanks eliminate the plastic components found on many factory radiators, helping deliver greater strength and long-term durability. CNC-machined fittings and a 30-point dimensional inspection ensure accurate fitment without modifications. Every unit is individually leak-tested and subjected to vibration, thermal-cycle, pressure, and corrosion testing.
