CSF 2023+ Honda Civic FL5 Type R / 2024+ Acura Integra DE5 Type S All-Aluminum Radiator (CSF #7221)
Take your FL5 Civic Type R or DE5 Integra Type S to the next level with CSF's all-aluminum high-performance radiator. Engineered using race-proven tech from Honda Performance Development's TCR program, the CSF7221 radiator features cutting-edge 5mm multi-louvered fins and a 2-row 42mm core to improve heat dissipation by up to 25%.
With 100% TIG-welded aluminum construction and CSF’s exclusive B-Tube technology, this radiator outperforms the factory plastic tank design—making it a must-have for tuned builds, aggressive driving, and track use.
Expect a 6–8% drop in coolant temps—critical when running a larger intercooler or pushing your K20C1 turbo engine hard.
