⚡ SPARK PLUGS: SMALL PARTS. BIG JOB.
Your spark plugs may be small, but they play a huge role in how your engine runs.
They create the spark that ignites the air/fuel mixture inside your engine’s cylinders. When they’re worn, dirty, or failing, your vehicle may start letting you know:
🚗 Rough or shaky idle
⚡ Misfires or hesitation
⛽ Decreased fuel economy
🐌 Sluggish acceleration
🔑 Hard starting
💡 Check engine light
And sometimes… you may not notice much at all until the problem gets worse.
So how often should spark plugs be replaced?
It depends on the vehicle, engine, and type of spark plug. Some modern plugs are designed to last significantly longer than older styles, which is why it’s important to follow your vehicle manufacturer’s maintenance schedule.
A simple spark plug service can help keep your engine running smoothly, efficiently, and reliably.
Not sure when yours were last changed? 🤔
