What routine maintenance can prolong the life of spark plugs?

Regularly replacing and cleaning spark plugs is essential for prolonging their life because these components play a critical role in the engine's ignition process. Over time, spark plugs can accumulate deposits from fuel combustion, such as carbon buildup or oil residue, which can hinder their performance. By maintaining clean plugs, the spark plugs can create a stronger, more efficient spark, leading to better combustion and engine performance.

Additionally, monitoring their condition allows for the early detection of wear or damage, enabling timely replacements before they fail completely. This proactive approach not only extends the life of the spark plugs themselves but also helps prevent related issues in the ignition system and overall engine efficiency. Regular maintenance of spark plugs ultimately contributes to smoother engine operation, improved fuel economy, and reduced emissions.

The other options, while important in their own right, do not directly contribute to the maintenance of spark plugs. For instance, checking tire pressure is vital for safety and fuel efficiency but does not affect spark plug performance. Changing engine oil is critical for engine health but does not specifically extend spark plug life. Similarly, adjusting brake fluid levels is essential for brake performance, but it has no impact on the operation of spark plugs.
