HPS Performance 1.3 Bar High-Pressure Stainless Radiator Cap Type A | 1.3 Bar Pressure Rating | Cooling System Upgrade
Overview
The HPS Performance 1.3 Bar High-Pressure Stainless Radiator Cap Type A is a direct replacement for the stock radiator cap found on most Subaru models. Designed to hold a higher pressure than standard OEM caps, this radiator cap raises the boiling point of your coolant, allowing your cooling system to operate more efficiently under demanding conditions. Whether you drive a daily commuter, a spirited WRX STI, an off-road Crosstrek, or a custom build, this cap helps reduce the risk of overheating by maintaining optimal coolant pressure and temperature.
Engineered with durability and performance in mind, the HPS radiator cap features a stainless steel construction paired with upgraded silicone gaskets for a secure, long-lasting seal. This combination ensures resistance to harsh thermal environments and chemical exposure common in high-performance Subaru engines. The spring-loaded Type A design matches factory specifications for a seamless drop-in installation, maintaining OEM fitment and reliability while enhancing cooling system capabilities.
By increasing the coolant system pressure to 1.3 bar, this radiator cap effectively raises the coolant’s temperature limit, which is critical for Subaru owners pushing their vehicles in track, off-road, or high-load scenarios. This upgrade provides peace of mind and improved thermal management, helping to preserve engine longevity and performance during intense driving conditions.
