Product Details
The Honda OEM Exhaust Manifold Gasket is a genuine factory replacement designed for select Honda and Acura K24Z 2.4L engines, including the Honda Civic Si, Accord, CR-V, Crosstour, Acura TSX, and ILX. This gasket creates a secure seal at the exhaust manifold and primary catalytic converter connection, helping prevent exhaust leaks and maintain proper engine performance.
Over time, exhaust gaskets can deteriorate or become damaged from repeated heat cycles and engine operation. A leaking gasket may cause ticking noises, exhaust odors, increased exhaust noise, and reduced engine efficiency.
Manufactured to Honda's original equipment specifications, this gasket features durable stainless steel construction designed to withstand high exhaust temperatures and pressure. It's an excellent replacement during exhaust system repairs, header installations, K24Z engine rebuilds, and performance upgrades.
