Product Details
The MK3 Focus RS is no slouch it a performance benchmark straight from the factory. But when you start tuning that 2.3L EcoBoost or take it to the track, heat becomes your worst enemy. The OEM plastic tank and single-row aluminum core simply can't keep up. That where CSF High-Performance Radiator comes in.
Developed with input from EcoBoost tuning experts and motorsport teams, this radiator is a serious upgrade that offers better thermal management under the most demanding conditions. Whether you're pulling hard through canyon roads or hammering laps at the circuit, the triple-pass design ensures your coolant stays cooler, longer. Lower temps mean improved engine longevity, better performance, and more consistent power delivery.
Compared to stock, the CSF radiator boasts more fluid capacity, better airflow efficiency, and drastically improved cooling performance thanks in part to its exclusive B-Tube core and multi-louvered fin design. The all-aluminum, TIG-welded construction ensures this radiator will go the distance, resisting heat and pressure where others crack and fail.
