Spark plugs might be small, but they carry a heavy workload! They supply the spark that ignites the air-fuel mixture inside your engine cylinders thousands of times every minute.
What happens when spark plugs wear out?
- Rough Idling: The engine vibrates or produces a jerky, uneven sound while sitting at a red light.
- Poor Acceleration: Stepping on the gas pedal feels sluggish or delayed.
- Hard Starts: The engine cranks longer than usual before firing up.
Increased Fuel Consumption: Worn plugs cannot burn fuel efficiently, wasting gas.
Replacing spark plugs according to your manufacturer's schedule keeps your engine running smoothly and efficiently.
