Spark Plug
Rough idling, misfires, hard starts, or worse gas mileage often trace back to worn spark plugs. These small parts ignite the fuel in your engine, and when they wear out the engine runs rough and loses efficiency. We replace your spark plugs with the right type and gap so your engine runs smooth and strong again.

- Damaged plugs from engine oil leaking into cylinders
Frequently asked questions
How often should spark plugs be replaced?
It depends on the type. Copper plugs may last around 30,000 miles, while iridium or platinum plugs can last 60,000 to 100,000 miles. We can advise based on your vehicle.
What happens if I don't replace worn spark plugs?
Worn plugs cause misfires, rough running, harder starts, and worse fuel economy, and over time they can damage the catalytic converter or ignition coils.
Will new spark plugs improve performance?
Yes. Fresh plugs restore smooth idle, easier starting, and better fuel economy, especially if your old ones were worn or fouled.
