Weapon-R 626-113-101.B Throttle Body Thermal Barrier Gasket - 1NZ-FE

The Weapon-R 626-113-101.B is a high-temperature throttle body thermal barrier gasket engineered to replace the factory OEM throttle body gasket. Designed for 1NZ-FE engines, this performance upgrade targets one of the most common sources of heat soak in the intake system — heat transfer at the throttle body-to-intake manifold interface.

By insulating the throttle body from the heat generated by the cylinder head, this gasket helps keep incoming intake air cooler and denser, translating to improved combustion efficiency. Weapon-R claims gains of up to 5% more horsepower and torque compared to the stock OEM gasket.

Key Features:

• Direct OEM replacement — bolt-on fitment with no modifications required
• Constructed from high-temperature resistant thermoplastic rated to withstand up to 400°F
• Reduces thermal transfer between the cylinder head and throttle body
• Helps lower intake air temperature for improved volumetric efficiency
• Up to 5% horsepower and torque improvement over stock
• Manufacturer Part Number: 626-113-101.B

The Weapon-R thermal barrier gasket is a simple, cost-effective performance modification for enthusiasts looking to reduce heat soak without complex engine modifications.
