Why should I replace my spark plugs?
The spark plug is possibly the most integral component of the spark-ignition combustion engine. Each one sits at the top of a cylinder head in your engine to combust fuel-air mixture and fire up your vehicle. Combustion occurs through the transfer of electrons across the spark gap.
The Gap is the space between the curved L-shape of the ground electrode and the center electrode that runs through the center of the plug. As electrical current is supplied to the plug by the ignition coil or the magneto, a voltage difference builds up between the two electrodes.
Once the voltage is high enough, the current ionizes the gases in the fuel-air mixture, allowing the spark to travel across the gap from the center electrode to the ground electrode. The spark reaches temperatures around 60,000 Kelvin (That’s over 100,000 degrees Fahrenheit!)—hot enough to combust the fuel-air mixture.
Every time the plug sparks, some metal is removed from the electrode. This eventually wears out the spark plug. Plugs last right about 30,000 miles, and it is recommended to change them every 20-40,000 miles.
Do I have bad spark plugs?
Signs of bad plugs can be stalling, trouble starting, and engine misfires. Misfires lead to increased emissions, wasted gas, and reduced power—they can even overheat your catalytic converter. If your engine is misfiring, there is a good chance it’s time for new plugs. Don’t put your car at risk for more severe damage down the road. Shop at Yesautoparts.com.
