Handling incredible voltage levels, up to 100,000 volts, your Infiniti spark plug wires are a hard working part of your ignition system, essential to the proper starting and running of your vehicle. As they serve your vehicle, your Infiniti spark plug wires endure a great deal of wear and tear from the heat and high voltage, and you can expect to have to replace them about once a year. This routine vehicle maintenance procedure is usually done during your annual tune-up, which is made up of a series of procedures that focus primarily on the ignition system parts. The basic tune-up tasks are fairly simple, once you've learned to do them, and replacing your Infiniti spark plug wires is the easiest of the group, as long as you are smart about it. Rather than remove the whole set at once, it is far better and easier to replace your Infiniti spark plug wires one at a time. That way, there is no chance of mixing up the order of your new Infiniti spark plug wires, which will result in a vehicle that may not start or may gasp its way to a start and not be able to stay running or, if it is able to maintain, will run really rough, which will do nothing good for the health of the other parts under the hood, such as the other parts of ignition system and those of your combustion system. When you choose your Infiniti spark plug replacements, there's more to consider than just price, as there are a lot of cheaply made and priced spark plug wires that simply will not perform well enough to be worth what you save in cash, as they may be unable to take you through the year that they should last. With that said, however, you can get high quality replacements - wires that feature thick insulation, secure attachments that resist loosening from vibration, and are capable of reliably handling the high voltage that will pass through them - at a reasonable price when you choose your replacement Infiniti spark plug wires from our online catalog.
