Skunk2 359-99-0020 High-Pressure Radiator Cap Bar - 1.3

The Skunk2 High-Pressure Radiator Cap is engineered to improve cooling system performance by increasing internal radiator pressure to 1.3 kg/cm² (approximately 18.5 PSI), compared to the standard 1.1 kg/cm² found in OEM caps. This increased pressure physically raises the coolant boiling point, allowing the cooling system to operate more efficiently under demanding conditions.

Key Features:

• Higher pressure rating (1.3 kg/cm²) prevents coolant boil-over under high temperatures
• Raised boiling point increases cooling efficiency and system performance
• Ideal for high-load applications including racing, track days, and circuit driving
• Equally effective for street performance and daily driving applications
• Direct replacement for stock radiator cap
• Durable construction with precision-engineered pressure valve

By maintaining higher system pressure, the Skunk2 Radiator Cap helps prevent vapor pockets and coolant boil-over, ensuring consistent engine temperatures even during extended high-performance driving. This simple upgrade provides measurable benefits for both track-focused builds and spirited street machines.
