Maximize your Acura RSX's performance with this precision-engineered all-aluminum high-performance radiator designed specifically for 2002-2006 Type-S and base models. Built to handle the cooling demands of modified K20 engines, this radiator features CSF's advanced B-Tube technology delivering 15% increased heat transfer efficiency through specialized tube geometry and dual liquid laminar flow. The 2-row 42mm aluminum core provides significantly greater cooling capacity than fragile factory plastic-tank radiators, essential for turbocharged builds, all-motor high-compression engines, and aggressive street driving. CNC-machined end tanks with precision TIG welding eliminate the weak crimped joints that commonly fail on aging RSX radiators, ensuring leak-free performance throughout the vehicle's life. Ultra-efficient multi-louvered fins are wind-tunnel tested to maximize heat dissipation whether you're on the dyno, at the drag strip, or stuck in traffic. Drop-in fitment requires no modifications and accommodates all OEM quick-connect hoses, fans, and mounting brackets.
Protect your high-revving K-series engine from overheating damage during track days, autocross, and spirited canyon runs. Perfect for turbocharged RSX builds, K24 engine swaps, and naturally aspirated motors with aggressive camshafts and tuning. Eliminate cooling issues that cause blown head gaskets and warped cylinder heads on modified Hondas. Essential upgrade for Type-S owners pushing their motors beyond 8,000 RPM regularly. Maintains consistent coolant temperatures for optimal performance and prevents heat-induced knock. Bolt-on installation uses factory mounting points and hardware. Trusted by Honda tuning shops and RSX enthusiasts who demand professional-grade cooling reliability for high-performance applications.
