A: No "Check Engine" light: A bad coil can cause this dashboard light to illuminate. Replacing or upgrading the coil may turn the light off. More reliable starting: A worn ignition coil can prevent your engine from starting. Upgraded coils enhance starting capabilities and can help ensure your vehicle starts every time as it should without long crank times.Best performance: A broken ignition coil can make your engine run rough, cough, and backfire. These symptoms are caused by cylinder misfires and fouled spark plugs from a bad coil, which leads to a loss of power. Better gas mileage: When you install new ignition coils, your engine operates better. An engine that operates better operates more efficiently, which gives you more miles to the gallon.

A: $20-$50: On the lower end of this price range, you usually get just one ignition coil. The quality is there, but this is a breaker point-type coil for older vehicles. On the upper end of the range are coils for vehicles with electronic ignition systems. Your electronic ignition system may use two of these and you might want to replace both. The package you purchase has four, six, or eight coils, depending on the number of cylinders in your engine.$50-$75: These are coils for electronic or distributorless ignition systems. They fit mid-quality cars and trucks like Ford, Nissan, and Toyota with four, six, or eight cylinders. $75-$140: The coils in this range are for distributorless ignition systems also, but many are for high-end cars like Lexus, Lincoln, and Infiniti.

A: Always ensure you check fitment lists before purchasing ignition coils. Some coils may be incompatible with your car, resulting in breakage during installation. Most ignition coils come with a full list of compatible fitments. Ignition coils will typically operate for about 100,000 miles before they need to be replaced. However, to minimize inconveniences, check the status of your coils every time the check engine light comes on. We suggest buying more ignition coils than you need. A pack of eight is a great choice. To be on the safe side, keep an extra set just in case they need a quick replacement. If possible, choose ignition coils with a longer warranty. You can always return or exchange them if they malfunction. The coils serve their purpose, and you have peace of mind.

A: When you start noticing more misfires, delayed starts, and poor fuel management, it may be time for ignition coil replacement. It's also a good idea to follow your manufacturer's recommended maintenance interval.Though, usually a check-engine light is a symptom of a failing coil.

A: Make sure your ignition coils are not exposed to extreme temperatures. Even your unused ignition coils need to be stored in a dry place free from excess moisture and heat.

A: When ignition coils don't function optimally, fuel doesn't burn as efficiently. You might notice stumbling under acceleration, a slightly roughened idle, decreased fuel economy, or other poor running conditions.
