CSF's all-aluminum 2-row radiator for 2014–2018 Subaru Forester upgrades cooling with a 42mm dual-pass core that increases fluid capacity and heat dissipation. Exclusive B-Tube Technology boosts heat transfer about 15% over standard oval-welded tubes, while multi-louvered fins maximize airflow. TIG-welded aluminum end tanks and plug-and-play drop-in fitment require no trimming. It's built to handle heavier duty off-road and turbocharged operating conditions and is individually tested.
