Spark plugs are a vital component of your vehicle, and are also one of the hardest working. The average spark plugs fires up to 400 times per minute per cylinder, which is why these small parts need to be replaced periodically. Worn spark plugs can lead to engine damage, reduced fuel efficiency, and poor engine performance such as misfiring and sluggish acceleration.

It is important to have your vehicle inspected if you notice any of the following symptoms:

- Rattling, knocking or pinging noises coming from the engine
- Hard vehicle start
- Reduced vehicle performance
- Decreased fuel efficiency
