Material Characteristics – PTFE

• Completely resistant to almost all automotive chemicals, solvents, and fuels
• Continuous thermal resistance up to +260°C
• Short-term temperature tolerance up to +300°C
• Non-melting, self-extinguishing, highly fire-resistant (UL94)
• Extremely low thermal conductivity: 8 × 10⁻⁴ cal/s/cm/°C

Why use a thermal PTFE gasket?

By reducing heat transfer from the cylinder head to the intake manifold, the gasket helps lower intake air temperatures, improves throttle response consistency, and reduces heat soak during long drives or spirited driving.

FAQ – Thermal Intake Gaskets

Does this gasket fit all intake manifolds for these engines?
Fitment depends strictly on the listed engine codes. If your intake manifold matches the standard D-series pattern for these engines, the gasket will fit correctly.

Do I need any modifications when installing a PTFE gasket?
No. Clean both surfaces thoroughly and torque bolts evenly. The 3 mm thickness does not require adjustments in stock setups.

Will this gasket improve power?
Its primary function is thermal insulation. Any performance improvement depends on overall setup, ambient temperature, and tuning.

Can PTFE withstand long-term engine heat?
Yes — PTFE is designed for continuous exposure to high temperatures and is chemically inert, making it highly durable.
