Weapon R Honda Civic R18 Cylinder Head Intake Manifold Thermal Gasket

The Weapon R Intake Manifold Thermal Gasket is a performance-focused upgrade designed to reduce heat transfer from the engine head to the intake manifold. By using a thermally resistant material, this gasket acts as a barrier between high engine temps and your intake charge, helping to lower intake air temperatures (IAT) for improved power and efficiency.

Under high-load driving or forced induction, heat soak can rob your engine of power. The Weapon R thermal gasket minimizes heat soak between the cylinder head and intake manifold, keeping the intake air cooler, denser, and more oxygen-rich. This leads to better combustion, improved throttle response, and reduced detonation risk.

Precision CNC-cut for exact OEM fitment, this gasket installs with zero permanent modifications. It’s a smart upgrade for both naturally aspirated and turbocharged setups, offering real-world gains with no downsides.

• Reduces heat transfer between cylinder head and intake manifold
• Lowers intake air temperature for denser, more oxygen-rich air
• Improves throttle response, combustion efficiency, and power
• Minimizes detonation risk in high-heat or high-boost applications
• CNC-cut for perfect OEM fitment; no permanent mods required
• Durable, high-temp material maintains seal integrity over time
