1-Row 31mm High-Performance Aluminum Radiator

• 2008-2014 Subaru | WRX STI
• 2008–2021 Subaru | WRX

CSF 1-Row 31mm High-Performance Aluminum Radiator for the 2008-2014 Subaru WRX and WRX STI and the 2015-2021 Subaru WRX with manual transmission. CSF updated this radiator with its "Multi-Fit" combo pipe and plug design (included), so one radiator covers both generations of cars. It supersedes CSF #7028.

The slim 1-row, 31mm core uses CSF's exclusive B-Tube technology - the B-shaped tubes increase heat transfer surface area by approximately 15% over standard oval tubes - paired with 6.5mm tall ultra-efficient multi-louvered fins for maximum surface area contact. The core and end tanks are 100% aluminum with TIG-welded construction, replacing the factory radiator's plastic end tanks.

Frequently Asked Questions

Q: Which cars does the CSF 7094 fit?
A: It fits the 2008-2014 Subaru WRX, the 2008-2014 Subaru WRX STI, and the 2015-2021 Subaru WRX, all with manual transmissions.

Q: What's in the box?
A: The radiator itself, plus CSF's "Multi-Fit" combo pipe and plug, which are included so the same radiator fits both the 2008-2014 and 2015-2021 cars. Mounting hardware is not included - the radiator mounts with your OE hardware.

Q: Does it require any modifications to install?
A: No. It is a true drop-in fit that installs in the factory location with no modifications, trimming, or cutting, and the CNC machined brackets and OEM-style inlet/outlet let you reuse your factory hoses.

Q: How is it different from the factory radiator?
A: The factory radiator uses plastic end tanks crimped onto the core. The CSF 7094 is 100% aluminum with TIG-welded tanks, and its 1-row 31mm B-Tube core moves heat more efficiently than a standard oval-tube core while staying slim enough for tight engine bays and front-mount intercooler piping.

Q: Does it have a built-in transmission cooler?
A: No. There is no internal transmission oil cooler, and CSF specifies this radiator for manual transmission cars only.
