Greddy High Pressure Radiator Cap

The Greddy High Pressure Radiator Cap is a performance replacement radiator cap that raises the cooling system's pressure rating above that of a typical factory cap. A higher-pressure cap raises the coolant's boiling point. This helps resist boil-over and coolant loss in demanding driving such as spirited street use, track days, and modified engines.

Key Features:

• Higher pressure rating than a standard OEM radiator cap, which helps the cooling system hold pressure
• Designed to help reduce coolant boil-over under heavy load and high temperatures
• Available in different cap types and pressure ratings to suit different radiator neck designs
• Built from durable materials with a sealing gasket for a secure, leak-resistant fit
• Direct replacement for the stock cap with no modification required

Greddy is a well-known Japanese maker of tuning and cooling components. Its radiator caps are a simple, affordable upgrade for keeping engine temperatures under control. Choose the cap type and pressure rating that match your radiator neck and cooling system.
