Product Description

The **CSF 8303** is a high-performance, heavy-duty radiator built specifically for the 3rd-gen Ford Raptor and 14th-gen F-150, as well as compatible EcoBoost and supercharged applications. Its 2-row, 42 mm B-Tube core delivers a significant increase in coolant capacity and thermal efficiency, helping manage higher heat loads from boosting, towing, and performance driving.

CSF's innovative 5 mm louvered fins maximize the surface area in contact with airflow, while the B-Tube design further optimizes heat transfer. With a fully TIG-welded aluminum build and precision CNC brackets, this radiator offers serious durability and crash-resilience under demanding conditions.

Installation is clean and straightforward thanks to OEM-style quick-connect hose fittings and precise bracket design - no cutting or modification is required. Whether you're pushing your F-150 or Raptor via off-road trails, towing heavy loads, or just want better thermal stability, the 8303 brings top-tier reliability and performance.
