Original GM Spark Plugs
Spark plugs are what delivers the igniting spark for your engine's internal combustion. They help you start your car or truck and create the power it uses to run. Without a dependable OEM GM spark plug, your vehicle's ignition system wouldn't work, and your vehicle wouldn't run at all.
How Does a Spark Plug Work?
First, your engine's valves fill its cylinders with a combo of air and fuel. Second, its piston compresses the mix, making more energy available. Finally, the spark plug ignites it, forcing down the piston and turning your crankshaft.
Signs of Bad Spark Plugs
Eventually, ignitions can weaken, and sparks can get smaller because of wear and corrosion. The result is more than just worsening engine efficiency. Bad spark plugs can lead to misfires and outright failures to fire. Luckily, determining when to change spark plugs is straightforward. GM spark plugs are made of high-durability materials that enable them to withstand millions of ignitions before replacement is necessary. Many are designed for extended life. That's around 100,000 miles. But, if the lead gap between plugs widens or plugs corrode, they can break. This can lead to major engine cylinder damage, and repairing an engine can be expensive. Review your GM owner's manual to determine spark plug lifespan, and do not use any beyond their recommended mileage.
