Description
Unlock better cooling performance with a high pressure radiator cap designed to raise system efficiency without breaking the bank. By increasing the pressure rating to 1.3 kg, this upgrade elevates the coolant’s boiling point, helping prevent heat soak and vapor lock under demanding conditions. The result: cooling efficiency improved by 22 percent or higher, more consistent temperatures, and enhanced reliability for spirited driving, track days, or daily use.
Engineered for precise fitment on both OEM and popular aftermarket radiators, this cap delivers stable sealing and durable performance. Its robust construction resists deformation and leakage at elevated pressures, ensuring the cooling system maintains optimal pressure across a wide range of operating temperatures. Expect quicker heat transfer, reduced risk of overheating, and improved thermal management during extended idling or high-load runs.
Perfect for performance builds and maintenance-minded owners alike, this is one of the most cost-effective cooling upgrades you can make. Installation is quick and straightforward—simply replace the existing cap, verify compatibility with your radiator type, and enjoy immediate gains in system stability and efficiency.
NOTE:
Type N is used for OEM radiators including 92-03 Civic, 94-01 Integra, 02+ RSX, 07+ Honda Fit
Type S is used for Koyo and other aftermarket radiators and also OEM 88-91 Civic, 90-93 Integra, 97-01 Prelude.
