Koyo 23+ Honda Civic Type R (FL5) All Aluminum Radiator

If you're pushing your 2023+ Honda Civic Type R (FL5) hard on the track or in spirited street driving, keeping your engine cool is paramount. This all-aluminum radiator from Koyo is built to handle the extra heat generated when you're really working the engine. It's a direct replacement for your stock radiator, meaning it's designed to fit right into your existing cooling system without major modifications.

Koyo constructed this radiator entirely from aluminum, which is a great material for heat dissipation. The all-metal design means there are no plastic end tanks to worry about cracking or leaking under stress, which can be a common failure point on factory radiators. This robust construction helps ensure reliable cooling performance even when your Type R is running at its limits. The increased core thickness and fin density compared to stock are engineered to move more heat away from the coolant, helping to prevent overheating and maintain consistent engine temperatures during demanding use.

This radiator is a solid choice for Type R owners who want improved cooling capacity over the factory unit. It's designed to work with your existing hoses and fan shroud, simplifying the installation process. While it's a direct fit, it's always a good idea to inspect your coolant hoses and clamps for wear during the replacement process to ensure the entire cooling system is in top shape.
