Overview:

The Skunk2 Racing Radiator Cap is a high-pressure upgrade designed to enhance the cooling efficiency of your Scion vehicle. By increasing the internal radiator pressure, this cap raises the coolant boiling point, helping your engine maintain optimal temperatures even under demanding driving conditions. Ideal for enthusiasts who push their vehicles hard, whether on the street or track, this radiator cap helps protect your engine from overheating and supports consistent performance.

Engineered for a range of Scion models from 2004 through 2016, the Skunk2 Radiator Cap is a reliable and straightforward upgrade that complements your vehicle’s cooling system, especially when paired with Skunk2 silicone radiator hoses.

Key Features:

This high-pressure radiator cap offers several technical advantages that improve your vehicle’s cooling system performance:

• Increases radiator internal pressure to 1.3 kg/cm², which is 0.2 kg/cm² higher than most OEM caps, raising the coolant boiling point.
• Enhances cooling system efficiency, reducing the risk of overheating during high-load or spirited driving conditions.
• Designed to fit a wide range of Scion models, including xA, xB, tC, xD, iQ, iA, and iM from 2004 to 2016.
• Compatible with Skunk2 silicone radiator hoses Type B for optimal sealing and durability.
• Proven performance on both street and race vehicles, demonstrating reliability under demanding conditions.
• Simple bolt-on installation with OEM-style fitment, requiring no modifications.
• Constructed to meet or exceed OEM quality standards for durability and pressure retention.

Construction & Design:

The Skunk2 Racing Radiator Cap is engineered with precision to maintain a consistent and elevated pressure within your cooling system. Its robust construction ensures a secure seal and reliable operation under high temperatures and pressures. The cap’s valve is calibrated to open at 1.3 kg/cm², providing a higher threshold than standard caps to maximize coolant performance without compromising safety.

This design helps prevent premature coolant boiling and vapor lock, which can degrade engine performance and cause overheating. The cap’s compatibility with Skunk2 silicone radiator hoses ensures a tight, leak-free connection for enhanced system integrity.

Installation & Fitment:

The Skunk2 Racing Radiator Cap is a direct replacement for the factory radiator cap on compatible Scion models. Installation is straightforward and requires no special tools, cutting, drilling, or tuning. Simply remove your existing radiator cap and install the Skunk2 cap to immediately benefit from improved cooling system pressure.

• Direct OEM fitment for easy bolt-on installation.
• No modifications or special tuning required.
• Compatible with factory radiator neck and Skunk2 silicone radiator hoses Type B.

What's Included:

• One Skunk2 Racing High-Pressure Radiator Cap (Type B)

Ideal For:

This radiator cap is perfect for Scion owners who want to enhance their vehicle’s cooling system performance, especially those who engage in spirited driving, track days, or experience high engine loads. It is also an excellent upgrade for daily drivers seeking improved reliability and thermal management without complicated modifications.

• Performance enthusiasts upgrading cooling efficiency.
• Street drivers aiming for better engine temperature control.
• Track and race car owners requiring reliable high-pressure cooling components.
