Thermal Gaskets for Honda – PTFE 3 mm Intake & Throttle Body Gaskets

In this category you will find thermal gaskets made from 3 mm PTFE (Teflon) dedicated to Honda engines – mainly for the joint between the cylinder head and intake manifold, and between the manifold/plenum and throttle body. They are designed for popular Honda platforms and engines (B-series, D-series, K-series, H/F/J-series) used in Civic, Integra, Accord, CR-X and other classic Honda models.

Why use PTFE thermal gaskets on Honda engines?

Thermal gaskets reduce heat transfer from the hot cylinder head into the intake manifold and throttle body. For Honda engines that often work at high RPM and high load, this means:

• Lower intake air temperature – less heat soak of the manifold and throttle body.
• More stable performance – more consistent power delivery on track days, hot summer drives and long highway runs.
• Better protection for plastic and aluminum manifolds – reduced thermal stress on OEM and aftermarket parts.
• Improved reliability – less risk of knock in tuned engines and more repeatable conditions for ECU mapping.

Applications – intake manifolds and throttle bodies

Our Honda thermal gaskets are cut from 3 mm PTFE and designed specifically for:

• Flange between cylinder head and intake manifold in popular Honda engines (B/D/K/F/H/J).
• Flange between throttle body and intake manifold / plenum.
• Both OEM manifolds and selected aftermarket intakes and throttle bodies designed for Honda engines.

Where we do not stock a ready-made thermal gasket for a specific manifold or throttle body, it may still be possible to supply it: aftermarket manifolds and throttle bodies for Honda can often be covered on a made-to-order basis. Details are listed in individual product descriptions or available on request.

Material properties – PTFE (Teflon) 3 mm

• Excellent thermal insulation – very low thermal conductivity compared to standard gasket materials.
• High temperature resistance – continuous operation up to approx. 260 °C and short peaks up to around 300 °C.
• Chemical resistance – fully resistant to fuels, oils, coolants and common automotive chemicals.
• Dimensional stability – 3 mm thickness ensures effective insulation while maintaining sealing performance.

Custom thermal gaskets for Honda – made to order

If you are using a custom intake manifold, individual throttle bodies or a rare Honda setup, we can often prepare a custom PTFE thermal gasket. To do so, we need either:

• a sample gasket (OEM or aftermarket) to copy, or
• the intake manifold or throttle body itself to use as a template.

This allows us to match bolt patterns, ports and shapes precisely, while keeping all the benefits of 3 mm PTFE insulation.

FAQ – Honda Thermal Gaskets

Do Honda thermal gaskets fit both OEM and aftermarket manifolds?
Each gasket is designed for specific applications. Many are made for OEM intake manifolds and throttle bodies; some also match popular aftermarket parts. Always check the product description or contact us with your engine code and manifold/throttle model.

How is a 3 mm PTFE gasket installed?
Installation is similar to a standard gasket. Surfaces must be clean and flat, bolts torqued evenly, and clearance checked for the extra 3 mm thickness (for example at brackets, supports or fuel rail).

Can you make a custom thermal gasket for my Honda?
Yes, in many cases it is possible. We need either another gasket to copy or the manifold / throttle body itself to take accurate measurements. Contact us to discuss details before sending any parts.

Is this only for performance builds?
No. Thermal gaskets are popular in tuning and motorsport, but they also work very well in daily-driven Hondas, helping to stabilize operating conditions and reduce heat soak in the intake system.
