Replace your worn or leaking Honda / Acura K-Series header gasket with the Velocity K-Series copper header gasket for K20 and K24 engines. Designed for the primary header flange between the cylinder head and exhaust header, this gasket is a practical option for header installs, exhaust leak repairs, engine swaps, and K-Series performance builds.
Copper exhaust gaskets are commonly used in high-heat applications because copper provides strong thermal conductivity and distributes heat evenly. This helps reduce heat-related gasket failure while creating a tighter seal than many standard steel exhaust gaskets.
This gasket fits select Honda and Acura K-Series engines including K20A3, K20A2, K20Z1, K20Z3, K24A2, and K24A4 applications. It is commonly used on RSX, Civic Si, TSX, Accord 4-cylinder, and JDM DC5 Integra Type R K-Series header setups.
