Product Details
If you're working on the engine of your 2006-2009 Honda Civic Si, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing the combustion chamber. It's specifically made for the K20Z3 engine and features an 86mm bore with a .040 inch thickness, making it a direct fit for your Si.
This gasket is built with three to five layers of stainless steel. Cometic chose stainless steel because it's strong, resists corrosion, and can rebound well under pressure.

This coating helps ensure a good seal even in tough conditions and on various surface finishes.
