This is a genuine HONDA Valve Stem Seal B, part number 12211PE0003. It is a critical component for your engine's internal sealing system. The valve stem seal's primary function is to prevent oil from entering the combustion chamber through the valve guides. A worn or damaged seal can lead to increased oil consumption, blue smoke from the exhaust, and fouled spark plugs, ultimately impacting engine performance and longevity. Crafted to HONDA's exacting standards, this seal provides a durable and effective barrier against oil leakage. Its precise design ensures a perfect fit on your specific HONDA model, guaranteeing optimal function and preventing premature wear. Replacing worn valve stem seals is a crucial maintenance task that can restore your engine's efficiency and help it run smoother for longer. This part is essential for maintaining the integrity of your engine's lubrication system. By preventing oil from seeping past the valve stems, it helps to keep the combustion process clean and efficient. This not only improves performance but also reduces emissions and extends the life of other engine components like catalytic converters and spark plugs.
