Product Details
The Honda OEM 87mm Cylinder Head Gasket is a genuine factory replacement designed for the 2004-2008 Acura TSX equipped with the K24A2 2.4L DOHC i-VTEC engine. Manufactured to Honda's original equipment specifications, this multi-layer steel (MLS) head gasket provides a dependable seal between the cylinder head and engine block, helping maintain proper cylinder compression while preventing engine oil, coolant, and combustion gases from leaking between passages.
The cylinder head gasket is one of the most critical sealing components in your K-Series engine. It must withstand high combustion pressures, extreme operating temperatures, and repeated thermal expansion while maintaining a reliable seal. A damaged or failing head gasket can lead to coolant loss, overheating, reduced compression, oil contamination, and decreased engine performance.
Featuring a design compatible with the factory 87mm cylinder bore, this genuine Honda head gasket is engineered for the K24A2 engine's original cylinder head and block configuration. Its multi-layer steel construction provides durability and consistent sealing performance when installed on properly prepared mating surfaces.
In addition to its factory Acura TSX application, this head gasket is a popular choice for compatible K24 engine rebuilds, K-Series engine swaps, and K20/K24 hybrid builds using a K24A2-style cylinder head configuration.
Whether you're repairing a blown head gasket, rebuilding your K24A2, replacing a cylinder head, or completing a performance-oriented K-Series project, this genuine Honda replacement delivers the precise fitment and dependable quality expected from original equipment components.
