Weapon R Thermal Intake Manifold Gasket

2004–2006 Scion xA / xB 1NZ-FE Engine

Part #: 626-113-101

Overview

The Weapon R Thermal Intake Manifold Gasket is a high-performance replacement gasket designed specifically for the 2004 to 2006 Scion xA and xB models equipped with the 1NZ-FE engine. This innovative gasket replaces the OEM intake manifold gasket and is engineered to reduce heat transfer from the cylinder head to the intake manifold. By insulating the incoming air from engine heat, it helps maintain cooler, denser air charge for improved combustion efficiency.

Ideal for enthusiasts looking to extract more power and torque from their naturally aspirated 1NZ-FE engine, this gasket offers a simple yet effective upgrade that can deliver noticeable performance gains without extensive modifications.

Key Features

The Weapon R Thermal Intake Manifold Gasket incorporates advanced materials and design to enhance engine performance and reliability. Key features include:

• High-temperature resistant construction capable of withstanding up to 400°F
• Special insulating material that reduces heat transfer from the cylinder head
• Improves intake air density by maintaining cooler temperatures
• Potential to increase horsepower and torque by up to 5%
• Direct OEM replacement for a perfect fit and easy installation
• Durable plastics designed for long-lasting performance under thermal stress
• Compatible with stock intake manifold and engine components
• Enhances throttle response and overall engine efficiency

Construction & Design

The gasket is crafted from high-temperature resistant plastics engineered to endure the demanding thermal environment of the intake manifold area. This material choice ensures the gasket maintains its integrity and sealing properties even under prolonged exposure to heat up to 400°F. The design focuses on minimizing heat conduction from the cylinder head to the intake manifold, effectively insulating the incoming air charge.

Precision manufacturing guarantees a seamless fit that matches OEM specifications, preventing vacuum leaks and ensuring reliable sealing performance. The gasket’s robust construction also contributes to improved engine reliability by reducing thermal stress on intake components.

Performance & Sound

By reducing heat soak into the intake manifold, the Weapon R Thermal Intake Manifold Gasket helps maintain cooler intake air temperatures. Cooler air is denser, allowing for more efficient combustion and improved engine output. This thermal barrier can translate into up to a 5% increase in horsepower and torque, enhancing overall vehicle performance without the need for additional forced induction or tuning.

While this gasket does not directly affect exhaust sound, the improved combustion efficiency can lead to a smoother and more responsive throttle feel, contributing to a more engaging driving experience.

Installation & Fitment

Installation is straightforward as this gasket is designed as a direct OEM replacement for the intake manifold gasket on 2004–2006 Scion xA and xB models with the 1NZ-FE engine. No modifications to the intake manifold or cylinder head are required. It is recommended to follow standard gasket replacement procedures, including cleaning mating surfaces and using proper torque specifications to ensure a reliable seal.

This upgrade is suitable for both professional mechanics and knowledgeable enthusiasts comfortable with basic engine maintenance.
