Although they are small, the spark plugs on your GM vehicle perform a big job. Spark plugs are located inside the cylinder of the vehicle and they convert electricity into a spark. That spark is used to ignite the mixture of fuel and air that comes through the fuel system and to provide power for the vehicle. If a spark plug isn't working properly, your ignition system as a whole will suffer. Typically, if you are having problems with starting your vehicle it might be time to change your spark plugs. Carbon build up can cause spark plugs to go bad over time. How many spark plugs you need will depend on the size of your engine. When purchasing spark plugs look to replace them with OEM spark plugs. Buying OEM will ensure that your vehicle's engine is getting the right amount of power and that the electricity running through is converting in the right way. Without the spark plugs that are designed for the specific GM vehicle that you have, they may not be able to power the vehicle properly. It is often recommended that spark plugs be replaced every 20,000 to 40,000 miles. Shop our webstore for quality OEM spark plugs for your GM vehicle.
