How do I know if I need spark plugs?
My car has been making some weird noises. I’m not sure why but I’m really hoping it’s nothing expensive. How do I know if I need spark plugs?

Sorry to hear that! To know if you need spark plugs, keep an eye on your dashboard for a warning symbol—and stay alert to engine misfires.
In addition, here are a few key signs that indicate you may be due for new spark plugs:
- Engine misfires
- Rough and noisy idling
- Difficult to accelerate smoothly
- Louder than normal when driving
- Reduced fuel efficiency (filling up your gas tank more often)
You don’t need to replace the spark plugs very often, so we recommend that you bring your vehicle to a skilled mechanic for assessment.
While most
car insurance
policies won’t cover general wear-and-tear damage—like needing new spark plugs—it’s still a good idea to get coverage for emergency situations. For instance, it’s easy to get roadside assistance
. The Jerry
app can help you assess your coverage options and look for the lowest possible rate. Good luck!
