Weapon R Thermal Throttle Body Gasket

2005–2010 Scion tC / 2008–2015 Scion xB 2AZ-FE

Part #: 626-113-103.B

Overview

The Weapon R Thermal Throttle Body Gasket is a high-performance upgrade designed specifically for Scion tC models from 2005 to 2010 and Scion xB models from 2008 to 2015 equipped with the 2AZ-FE engine. This specialized gasket replaces the OEM intake gasket and serves as a thermal barrier, reducing heat transfer from the cylinder head to the intake manifold. By minimizing heat soak, it helps deliver cooler, denser air to the engine, which can improve combustion efficiency and overall engine performance.

Ideal for enthusiasts seeking a simple yet effective way to increase power and torque without extensive modifications, this gasket offers a reliable solution to enhance throttle response and engine output. Its durable construction ensures long-lasting performance under demanding conditions.

Key Features

The Weapon R Thermal Throttle Body Gasket incorporates advanced materials and design features to optimize intake air temperature and engine performance. Key features include:

• High-temperature insulating material that withstands up to 400°F
• Reduces heat transfer from the cylinder head to the intake manifold
• Improves horsepower and torque by up to 5%
• Direct OEM replacement for a perfect fit and easy installation
• Compatible with 2AZ-FE engines in Scion tC (2005–2010) and xB (2008–2015)
• Durable construction resists warping and degradation over time
• Enhances throttle response by maintaining cooler intake air temperatures
• Lightweight design does not add unnecessary mass to the intake system

Construction & Design

The gasket is crafted from high-temperature resistant plastics engineered to endure continuous exposure to elevated engine bay temperatures up to 400°F. This material choice ensures the gasket maintains its insulating properties and structural integrity over time, preventing heat soak that can degrade engine performance. The precision molding guarantees a seamless fit between the throttle body and intake manifold, eliminating air leaks and maintaining optimal airflow.

Weapon R’s focus on thermal insulation addresses a common performance bottleneck in naturally aspirated engines by reducing intake air temperature, which directly contributes to improved combustion efficiency and power output.

Performance & Sound

By reducing heat transfer to the intake air, the Weapon R Thermal Throttle Body Gasket helps deliver cooler, denser air to the engine’s combustion chambers. This results in a measurable increase in horsepower and torque—up to 5%—which can translate to improved acceleration and throttle response. While the gasket itself does not alter exhaust sound, the enhanced engine efficiency may contribute to a more responsive driving experience.

Installation & Fitment

Installation is straightforward and designed to be a direct replacement for the factory throttle body gasket. No modifications or special tools are required, making it suitable for both professional installers and knowledgeable enthusiasts. Simply remove the OEM gasket and install the Weapon R Thermal Throttle Body Gasket in its place, ensuring a clean and secure seal.

This gasket is specifically engineered to fit Scion tC models from 2005 through 2010 and Scion xB models from 2008 through 2015 equipped with the 2AZ-FE engine, ensuring compatibility and optimal performance.
