Blox Racing Radiator Cap

The Blox Racing Radiator Cap is a high-pressure replacement radiator cap. It helps your cooling system handle the pressure that builds as coolant heats up. Blox Racing caps are rated at 1.3 bar. Standard caps are designed to open at about 1.1 bar.

Key Features:

• 1.3 bar pressure rating, higher than the roughly 1.1 bar of a standard cap
• Relieves excess pressure so heat is released and coolant flows into the overflow tank
• Helps the radiator resist overheating under higher heat and pressure
• Improves cooling efficiency and performance
• Available in multiple cap styles (Type A and Type B) to suit different radiator and filler neck designs

This is a simple, low-cost upgrade for street, track, and performance builds. It drops in to replace the existing radiator cap. Check that the cap style matches your radiator or filler neck before ordering.
