A spark plug assembly (SPLZFR5C11) is a small but critical car component that ignites the air-fuel mixture inside the combustion chamber of your engine. This ignition is necessary for starting your engine and producing power consistently.

These essential engine components are designed to withstand the extreme heat and pressure from your engine cylinders. However, these assemblies are still prone to wear and tear. Most spark plugs should be replaced every 20,000 to 40,000 miles, depending on the manufacturer’s recommendations. Some signs of busted spark plug assemblies include poor acceleration and fuel economy, and engine misfires. If you’re having a more difficult time starting your engine than usual, your spark plugs might be compromised and need to be replaced immediately.
