Spark plugs light the fuel mixture in your car’s engine, powering it to move. It receives a spark from the electronic ignition in modern cars or the distributor cap and rotor in vintage automobiles, sitting on top of your engine’s cylinder head.

Finally, conventional spark plugs will wear out at around 30,000 miles to as much as 40,000 miles. Conventional spark plugs will eventually wear out due to excessive use and end up causing stalling, starting difficulties, and engine misfires. Higher-cost platinum-tipped spark plugs may not have to be changed as often. At the same time, it’s a good idea to replace your oxygen sensor, spark plug wires, PCV valve, and fuel filter.
