Thermal Gaskets PTFE 3 mm – Thermoshield Intake and Throttle Body Gaskets

Thermal gaskets made from PTFE (Teflon) 3 mm thick effectively reduce heat transfer between the cylinder head, intake manifold, throttle body, and plenum. This helps stabilize intake air temperature, improve reliability of engine components, and ensure consistent performance even under demanding driving conditions.

Why choose PTFE thermal gaskets?

• Excellent thermal insulation – PTFE minimizes heat conduction between engine components, keeping the intake system cooler.
• High temperature resistance – continuous operation up to approx. 260°C and short-term peaks up to 300°C.
• Chemical resistance – completely resistant to fuels, oils, lubricants, and common automotive fluids.
• Precision fit – perfectly matched shapes and bolt patterns for popular Japanese engines, especially Honda.
• Durability and low friction – PTFE offers long-term stability and does not degrade over time.

Where to use thermal gaskets?

• Between intake manifold and cylinder head – to reduce heat transfer from the head to the intake.
• Between throttle body and manifold/plenum – to prevent heat soak in the throttle housing.
• Drive-by-wire and mechanical throttle bodies – to stabilize throttle response and improve engine consistency.

Thermal gaskets are a popular upgrade among tuners, but they are equally beneficial in daily-driven vehicles. By lowering the intake air temperature, they help maintain power consistency, reduce knock risk, and improve engine longevity.

FAQ – Thermal Gaskets / Thermoshield Gaskets

What’s the difference between a thermal gasket and a standard gasket?
Thermal gaskets made from PTFE have a much lower thermal conductivity, meaning they better isolate the intake manifold and throttle body from engine heat.

Do they require modifications for installation?
Most PTFE gaskets are plug-and-play. Ensure both surfaces are clean, torque evenly, and verify clearance for the extra 3 mm thickness.

Do thermal gaskets increase power?
The main goal is to reduce heat transfer, stabilize air temperature, and improve efficiency. Any power gains depend on the engine setup, ambient conditions, and tuning.

What are the material limits?
PTFE is chemically inert and stable under high temperatures — continuous operation up to about 260°C and short-term peaks near 300°C.

Which engines are these gaskets for?
Our thermoshield gaskets are precision-cut for popular Japanese engines, including various Honda intake and throttle applications. Check individual product listings or contact us for fitment assistance.
