A combustion engine needs three essentials to start and operate: gas, air, and a spark. Spark plugs are the little devices that provide the necessary spark from the pistons to ignite the air and fuel mixture to help your engine run. When they are improperly installed or worn out, your vehicle will stop running.
Spark plugs are one of those vehicle components that should be checked on a regular basis. When you bring your car, SUV, or truck to our auto repair shop for service, we can keep you updated on the condition of your spark plugs and replace them before they can become an inconvenience to you.
