What Is a Head Gasket and Why Is It Important?
The head gasket is a critical component in any internal combustion engine. It sits between the engine block and cylinder head, sealing the combustion chambers and separating the engine's oil and coolant passages. A high-quality head gasket ensures that the engine maintains proper compression while keeping coolant and oil from mixing or leaking. If the head gasket fails, it can lead to overheating, poor engine performance, and even catastrophic engine damage.
That’s why using a genuine Honda MLS head gasket like the 12251-P5M-004 is so important—especially for performance-oriented engines like the H22A4. It provides long-term reliability, superior sealing, and peace of mind whether you're daily driving or running at redline.
