This Cometic head gasket has an 87mm bore. This is the standard bore size for the K20Z3 engine found in the 2006-2009 Honda Civic.

What is the purpose of the Viton coating?

The Viton rubber coating on the outer layers of the gasket helps it meet the demands of harsh sealing environments and varying surface finishes. It's heat resistant up to 482°F (250°C), ensuring a reliable seal under high temperatures.

About this part

Product Details

If you're rebuilding the top end of your 2006-2009 Honda Civic, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made for the K20Z3 engine and features an 87mm bore, which is the standard size for this application. A good head gasket is crucial for keeping your engine's combustion chambers sealed from the coolant and oil passages, preventing serious issues like overheating or oil contamination.

This gasket is built with three to five layers of stainless steel. Using stainless steel gives it extra strength and helps it resist corrosion, while also allowing it to rebound well under pressure. The outer layers are treated with a special Viton rubber coating on both sides. Viton is known for handling high temperatures, up to 482°F (250°C), and it holds up well in tough sealing conditions and on various surface finishes, ensuring a reliable seal even when your engine is working hard.
