Product Details
| Part Number: | HYB-RAC-01-04 |
| Brand: | Hybrid Racing |
| Color: | Black |
Upgrade your cooling system with the Hybrid Racing HYB-RAC-01-04 High-Pressure Radiator Cap. Designed for performance Honda and Acura applications, this Type D radiator cap increases cooling-system pressure to 1.3 bar (18.85 PSI) compared with the typical factory 1.1-bar cap. The increased system pressure raises the coolant's boiling point, providing additional protection against coolant boiling and cavitation during demanding driving conditions.
Whether you're building a daily-driven street car, naturally aspirated track setup, or high-performance turbocharged Honda, maintaining consistent coolant pressure is critical. The Hybrid Racing high-pressure cap is a simple upgrade that can provide additional cooling-system headroom during high engine loads, hot weather, and extended track use.
The HYB-RAC-01-04 uses the Type D cap design and fits a wide range of Honda and Acura applications, including many Civic, Integra, RSX, S2000, Accord, TSX, Element, Fit, and Civic del Sol models. Hybrid Racing specifically notes that Type D and Type F radiator caps are physically different and are not interchangeable, so radiator neck compatibility should always be verified before ordering.
