Other symptoms can include rough idling and stalling. If your engine seems to be running rough, or skipping, chances are good that it’s time to have your plugs replaced.

Drivers with a lighter foot will enjoy longer life from their plugs. High Revs: If you regularly “put your car through its paces,” you’ll put additional wear and tear on your spark plugs, meaning that you’ll need to replace them more often. Not only does that mean you’ll need to replace a blown seal, but it means your spark plugs will need to be changed more frequently because of contamination. Just as your veins distribute the blood from your heart throughout your body, powering your every movement, a wiring harness distributes electricity from your vehicle’s primary fuse box and delivers it to the various electrical systems throughout your vehicle. If there is oil present, it means there’s a leak. Your car’s engine wiring harness is much like your body’s circulatory system. Oil Leaks: When you pull a spark plug out of the engine, the base should be relatively clean. Look for plugs made from iridium or platinum for the longest life (copper has the shortest lifespan – generally about 20,000 miles). Their electrodes do not wear down as quickly, meaning that you won’t need to replace them as frequently. Long Life: Some spark plugs are made to have a longer life. High Performance: If you have high performance spark plugs, it’s possible that you will need to replace them more often, as the electrode can wear down faster. However, the actual timing of replacement will vary depending on other factors.
That’s fine if you’re using stock spark plugs. If you check your owner’s manual, you’ll probably find that your automaker recommends you replace your spark plugs roughly every 30,000 miles. Eventually, it becomes so worn that it doesn’t create as much (or any) electric arc, which has a direct and immediate effect on your engine operation. Through normal use, the electrode on each spark plug does wear down. That center rod is the electrode – electricity arcs from that to the hook. The other end is bulbous, with a small metal rod coming out of the center, and a metal hook to one side. If you look at a spark plug, you’ll notice one end is narrow and tapered – this is where the wire connects to it. The primary type of wear here is with the electrode. Like most other components of your engine, spark plugs wear down over time. This is what ignites the fuel in your engine’s cylinders, creating the combustion that pushes the pistons down and actually turns the engine. Electricity is created by the alternator and sent to the plugs, which create arcs of electricity. Spark plugs connect to wires that lead to the ignition system.
It’s needed to operate most of your accessories, but is also required to make the engine run. While your engine runs on gasoline, it also requires electricity.
