CSF 7221 All-Aluminum 2-Row 42mm Radiator for 2023-2026 Honda Civic Type R & Acura Integra Type S
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2023-2026 Honda Civic Type R (FL5) and 2024-2025 Acura Integra Type S (DE5).
The CSF 7221 is a high-performance all-aluminum cooling solution engineered for the K20C1 engine. Designed to address the thermal demands of track use and spirited driving, this radiator features a 2-row 42mm ultra-high-performance core that significantly increases fluid capacity and heat dissipation compared to the factory unit. Testing has shown a 6-8% decrease in engine coolant temperatures over the original equipment.
Utilizing CSF's exclusive B-Tube technology, the cooling tubes are reinforced with a center brace that increases the heat transfer surface area by approximately 15% over standard oval tubes. The core also incorporates 5mm tall multi-louvered fins to maximize airflow efficiency. This 100% TIG-welded aluminum construction replaces the plastic tanks of the OEM radiator, providing superior durability and longevity under high-pressure conditions.
