The spark plugs in your vehicle are one of the most critical components that keep your engine running smoothly. They play a vital role in igniting the fuel-air mixture in your engine’s cylinders, which ultimately powers your vehicle. Over time, spark plugs can wear out, and replacing them is essential to maintain your vehicle’s performance and fuel efficiency. But how many miles do spark plugs last? The answer is not straightforward, as it depends on various factors, including the type of spark plugs, driving conditions, and maintenance habits.
Factors Affecting Spark Plug Lifespan
Spark plug lifespan is influenced by several factors, including:
