CSF 7209 Radiators - Aluminum

CSF manufactures the most advanced and efficient radiator in the industry for your 4th Gen Subaru Forester. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation..

The 2-Row 42mm aluminum core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF?s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. Efficiency is key in off-roading as speeds tend to be lower overall so you end up relying on the fans to move most of the air over the radiator. While the factory fans do a decent job pulling air through the radiator core, it is still less airflow than you?d typically see in city driving. A larger and more efficient core will keep your engine temps in check and keep your engine running strong. Additionally, the end tanks are made from high grade aluminum and TIG welded to the core for extra strength. In contrast, the OEM crimped onto plastic end tank design is much weaker and creates a weak point where failure is more likely. Because the CSF radiator is designed as a true plug-and-play drop-in fit application, installation requires absolutely no modifications, trimming, or cutting.
