Spark plugs may be small, but they have an outsized role in how well your car runs. These components ignite the air-fuel mixture in your engine’s cylinders, setting off the controlled explosions that power your vehicle. Over time, spark plugs wear down, and their performance declines — which directly affects acceleration, fuel efficiency, and overall drivability. Replacing spark plugs at the right intervals can breathe new life into your engine. Let’s explore how fresh spark plugs enhance performance and why staying on top of this maintenance is crucial for maintaining long-term vehicle health. Why Spark Plugs Are Important Every time you start your engine, spark plugs generate a small but powerful electrical spark to ignite the compressed fuel-air mixture. Without properly functioning plugs, the combustion process suffers. This can lead to misfires, inefficient fuel burning, and reduced power output. Fresh spark plugs provide consistent ignition ... read more
