Need new spark plugs? Here's what to expect.
Spark plugs are crucial to your car's performance, but they are easy and inexpensive to replace.

When spark plugs fire, each one creates a spark that ignites a mixture of air and gasoline in your car's engine; this combustion powers your car. The engine has one spark plug for each cylinder, and each plug fires around 1500 times a minute. When these plugs, or the wires that connect them to the distributor, wear out or get fouled, they do not fire when they should.
These misfires cause the cylinders in your engine to miss strokes. Think of it as your car having an irregular heartbeat. As a result, your car may run roughly, develop bad gas mileage and have trouble starting. If you let the problem go long enough, your car may not start.
When you notice the above symptoms, check the spark plugs and their wires first.

If bad spark plugs are the problem, what should you expect? Although a bad spark plug or wire is a serious problem, it is also one of the easiest and cheapest engine problems to fix.
The cost of spark plug replacements depends on where you go for service, as well as the make and model of your car. Take your car to the dealership for around $300 or less, or visit an independent mechanic for less than $200 on average. Shop around Atlanta mechanics before you commit.

You can usually finish the job in under an hour, depending on your skill level and how many plugs your engine has. Visit any Atlanta automotive store to buy spark plugs for $10 to $15 each.
Before you raise the hood, however, consider these factors:
Spark plugs are a vital part of your ignition system; fortunately, they are also simple and relatively inexpensive to fix, so do not put off this important piece of car maintenance.
