Maximize your cooling system’s performance with the Koyorad Type A Hyper Radiator Cap (Red / 1.3 Bar), available now at Terra Firma Automotive. Designed for serious tuners and performance enthusiasts, this premium Japanese-made cap is engineered to work seamlessly with Koyorad’s renowned all-aluminum racing radiators. By raising the system pressure to 1.3 Bar, this cap significantly increases the coolant’s boiling point—giving your engine greater resistance to overheating under high-performance and track conditions.

Most factory radiator caps operate at 0.9 Bar, limiting your cooling system’s potential. The Koyorad Hyper Cap elevates the boiling point of your coolant to over 267°F, delivering a measurable advantage in heat management when it matters most. Whether you're upgrading your street machine or preparing for demanding motorsports applications, this cap helps ensure consistent cooling efficiency by preventing premature boil-over and maintaining proper coolant circulation under pressure.

Not only is the Koyorad Hyper Cap highly functional, but it also adds a refined, race-inspired touch to your engine bay with its bold red finish and premium construction. Built to last, this cap exemplifies Koyorad’s dedication to precision and durability.

At Terra Firma Automotive, we stock only the most trusted performance components for Japanese vehicles. Don’t compromise on your engine’s thermal control—equip your cooling system with the Koyorad Type A 1.3 Bar Radiator Cap and stay one step ahead. Shop now and experience the difference precision pressure control can make.
