CSF Subaru Forester 2.5L 2014-2018 High-Performance Radiator

Whether you're running the stout 2.5L naturally aspirated motor or the hot 2.0L turbo engine, off-roading and overlanding can be a lot harder on a Forester than you might expect. Between dealing with traction loss, steep inclines, and the added weight of gear, there's almost always more strain on the engine, resulting in above-average operating temperatures that the factory radiator can struggle to keep up with, especially on the turbo models. CSF has a long and successful track record with high-performance, heavy-duty, off-road grade radiators, and CSF's Subaru line of all-aluminium radiators is genuinely among the most trusted options in competitive motorsports, with many race teams around the world trusting CSF to keep their cars cool.

The 2-row, 42mm heavy-duty core not only increases fluid capacity but also improves the core's ability to dissipate heat, using CSF's exclusive B-Tube technology to increase heat transfer by approximately 15% over regular oval welded tubes. Super-efficient, multi-louvered 6.5mm tall fins maximise airflow through the core, which matters especially in off-road driving, where lower speeds mean you rely more heavily on the factory fans to move air through the radiator than you would at typical city speeds. End tanks are made from high-grade aluminium and TIG-welded to the core for genuine strength, in contrast to the OEM's crimped-onto-plastic design, a well-documented weak point where failure is more likely, and the last thing you want is a radiator failing while you're far from civilisation. This is a true plug-and-play drop-in fit, requiring absolutely no modifications, trimming, or cutting to install.
