There are many important ignition components in your Infiniti vehicle, and you want to make sure they are all functioning properly. The ignition process allows you to start your car and get from place to place. The ignition coils are a part of this system and work to help convert a current sent from your battery to a higher voltage. This helps to ignite the fuel and start the engine. There is an individual ignition coil for each of the spark plugs in the system. It's important to pay attention to the condition of the ignition coils so that you can replace them if needed. If the coils are just starting to fail, one of the first things you might notice is backfiring of the engine. Another thing that might be impacted is your fuel efficiency. Misfiring and stalling can also be signs of coil problems. You can find the best OEM Infiniti ignition coils for sale here if you need new ones.
