What are Spark Plugs?

Spark plugs are an important part of your vehicle’s ignition system. Think of them as tiny bolts of lightning that help power your engine. Each cylinder in your vehicle's engine has a spark plug. Electricity from the vehicle's battery runs to the spark plugs, where it is used to ignite the air and fuel mixture in the engine. The power of the explosion forces the piston into the cylinder, which turns the crankshaft, which turns the wheels, which ultimately puts your vehicle in motion. Pretty nifty, right?

Symptoms of failing Spark Plugs

Poor engine performance

If your spark plugs are worn, your vehicle will lose some of its power. The engine will misfire and hesitate, and your car will have much slower acceleration and a rougher ride. These are all signs that your vehicle might need a spark plug replacement or repair.

Check engine light

Remember that time your check engine light came on, and then you drove a few thousand miles anyway, pretending it wasn’t actually on? How did that work out for you? Busted spark plugs will impact engine performance and emissions, which should illuminate your check engine light. Try paying attention to it this time, it might save you some money in repair or replacement costs. A check engine light is another great sign that you might need a spark plug replacement.

Regularly scheduled maintenance

We know. You don’t use maps and you don’t like chore charts and you don’t need to consult your regularly scheduled maintenance. Good for you. But actually, you do. Spark plugs are considered a part of maintenance, and you should replace these plugs before they die on the job.

How urgent is replacing Spark Plugs?

If a spark plug or two are dead, the car won’t be running on all cylinders, and you’d be a pretty bad friend if you let your car go to work while sick. Do you want dead sparks on your conscience?

The longer you drive with busted plugs, the more damage you risk incurring to your vehicle. Misfiring sparks can hurt the catalytic converter, and, in rare cases, a portion of the spark plug can fall off into the engine, causing some bigger issues and far more to replace than just a couple old plugs.

The simple thing is the right thing. Get a spark plug replacement on time and minimize the risk of having to replace your entire engine.
