Product Description

The CSF 7042 Race-Spec Radiator is built for 2008-2014 Subaru WRX and STI applications needing stronger cooling for street and track use. It uses 100 percent all-aluminum TIG-welded construction, a 2-row core, CSF B-Tube technology, ultra-efficient 6.5 mm tall multi-louvered fins, CNC-machined mounting brackets, and a polished silver finish.

CSF lists an increase in cooling efficiency of around 30 percent, helping keep temperatures under control when the car is pushed hard. The B-Tube core and multi-louvered fins increase surface-area contact, while the true drop-in design allows installation on supported applications without modifications.

The radiator includes a cap and fittings, uses CSF's multi-fit combo pipe and plug design, and is individually leak and pressure tested before release. This 7042 listing is tied to superseded CSF number 7095 and carries a limited 2-year warranty.
