Description

Secure your BRZ’s cooling system under demanding conditions with this performance-focused upgrade. The STI Radiator Cap increases the system’s opening pressure to prevent coolant overflow during spirited driving. As a result, it ensures consistent engine temperatures and reliability.

Product Highlights

Prevents Coolant Overflow Under High Load: This cap is engineered for performance driving. By raising the opening pressure from the standard 108kPa to 130kPa, it better contains coolant thermal expansion. Consequently, it prevents loss and maintains proper system volume during track use or aggressive street driving.

Enhances Cooling System Reliability: The higher pressure cap helps stabilize the cooling system. It allows the system to operate more effectively under stress. As a result, it contributes to consistent engine temperature management and protects against overheating in demanding situations.

Features STI Branding for a Technical Detail: The cap carries the STI logo, adding a purposeful, performance-oriented detail under the hood. Therefore, it signifies an upgrade focused on durability and readiness for increased engine loads.
