Why Change Your Spark Plugs?

Maintaining your vehicle's spark plugs is a crucial aspect of routine maintenance. Here are some reasons why it is essential to replace them:

Maintain Engine Performance

Spark plugs are essential for igniting the air-fuel mixture in each engine cylinder. Spark plugs can get worn, fouled, or corroded over time, resulting in weak or inconsistent sparks. This can lead to diminished engine performance, power, and fuel efficiency.
Improved Fuel Efficiency

Spark plugs that are in good condition create a strong, constant spark, resulting in efficient combustion. However, worn or fouled plugs can result in incomplete combustion and wasted fuel, lowering the fuel efficiency of your vehicle.
Reliable Starting

Worn or defective plugs can make starting the engine difficult, resulting in hard starting or misfires. Replacing this component guarantees reliable engine ignition in cold weather or difficult conditions.
