Generally, cars need new plugs every 30,000 miles or so, though some plugs can hold on for longer. Ignition coils, though, don\u2019t have a recommended mileage or age. Some last for the lifetime of the car while others conk out after 60,000 miles. Basically, until they go bad, you don\u2019t need to change them.<\/p>\n\n\n\n<p>Speaking of going bad, there are a few signs that foretell spark plug and\/or ignition coil failure. The most obvious is an engine misfire or backfire because without working plugs and\/or coils, fuel doesn\u2019t ignite properly. Your engine might also idle roughly, burn more fuel, have trouble starting, and make less power or deliver it less consistently. And these symptoms will likely come accompanied by a Check Engine Light.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-happens-if-you-don-t-change-your-spark-plugs-or-ignition-coils\"><strong>What Happens if You Don\u2019t Change Your Spark Plugs or Ignition Coils?<\/strong><\/h2>\n\n\n\n<p>On that note, mechanics usually change your spark plugs when you go in for a tune-up. This keeps your engine running smoothly and efficiently, which also extends its lifespan. And it\u2019s the same thing with your ignition coils.<\/p>\n\n\n\n<p>Besides being annoying and loud, misfires and backfires can cause internal engine damage if left unchecked. In addition, a damaged coil can overheat and create an oil leak, <a href=\"https:\/\/www.carbibles.com\/signs-of-bad-ignition-coil\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">experts<\/a> say. Not only can that lead to fouled spark plugs, but leaking oil can also short out other electrical connections. At that point, a bad ignition coil might be the least of your worries.<\/p>\n\n\n\n<p>Furthermore, age isn\u2019t the only thing that causes ignition coil failure. As the gap between a spark plug\u2019s electrodes grows, so does the energy the plug needs to make a spark. That means the coil needs to work harder, which makes it overheat and fail.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-here-s-how-you-can-change-your-car-s-spark-plugs-and-ignition-coils-at-home\"><strong>Here\u2019s How You Can Change Your Car\u2019s Spark Plugs and Ignition Coils at Home<\/strong><\/h2>\n\n\n\n<p>Fortunately, you can usually catch these failure signs before your car suffers permanent damage. And while it\u2019s a bit more involved than an oil change, most <a href=\"http:\/\/carlots.ng\/motoring\/5-things-you-do-mechanics-hate\">DIY mechanics<\/a> should be able to replace their spark plugs and ignition coils.<\/p>\n\n\n\n<p>First, make sure you have the correct replacement parts. You don\u2019t have to spring for the most expensive spark plugs or ignition coils. But make sure the ones you buy have the right specs and fit for your car. Also, if you don\u2019t already know, write down the torque specs for the plugs and any bolts or screws.<\/p>\n\n\n\n<p>Next, assemble your tools. Because this process requires precision, torque wrenches are a must. Plus, in addition to the usual socket wrench, sockets, extensions, and screwdrivers, you\u2019ll need a spark plug socket and gap tool. The former is vital because dropping the plug can damage it and your engine. Hence these sockets have rubber gaskets to securely hold the plugs.<\/p>\n\n\n\n<p>Once you\u2019ve got everything assembled, pop your hood, and disconnect your battery. Then, remove any intakes, covers, etc. until you can see the ignition coils. The next steps will change slightly based on what kind of ignition system your car has.<\/p>\n\n\n\n<p>If you have a distributor or a coil pack system, you\u2019ll see a bunch of thick wires stretching from it to the spark plugs. Meanwhile, my Abarth has a coil-on-plug system, which puts the coil right on top of the plug. Rather than thick wires, each coil-on-plug arrangement is hooked into the wiring harness. Since this is the most common system nowadays, I\u2019ll focus on it for the rest of this guide.<\/p>\n\n\n\n<p>Going one cylinder at a time, unclip the coil from the wiring harness and remove any securing bolts. Then, pull up the coil until it pops out. After that, use your spark plug socket to remove the old plug. Next, after checking the new plug\u2019s gap, start hand-threading it back into place.&nbsp;<\/p>\n\n\n\n<p>Once you\u2019re absolutely sure you haven\u2019t cross-threaded it, use your torque wrench to secure it.<\/p>\n\n\n\n<p>Then, take the new coil, smear a little dielectric grease on the end that connects to the spark plug, and securely re-install it. You should feel a little click when it grips the plug.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-yoast-seo-related-links\"><li><a href=\"http:\/\/carlots.ng\/motoring\/public\/blog\/car-tips-how-to-know-if-its-your-spark-plugs-or-ignition-coil-thats-bad\">Car Tips: How to Know if It\u2019s Your Spark Plugs or Ignition Coil That\u2019s Bad<\/a><\/li><li><a href=\"http:\/\/carlots.ng\/motoring\/public\/blog\/how-to-know-your-car-needs-a-new-ignition-coil\">How to Know Your Car Needs a New Ignition Coil<\/a><\/li><li><a href=\"http:\/\/carlots.ng\/motoring\/public\/blog\/should-i-buy-the-2020-hyundai-palisade-or-the-2020-kia-telluride-top-secret-revealed-on-which-you-should-buy\">Should I Buy the 2020 Hyundai Palisade or the 2020 Kia Telluride?

Finally, re-install any intakes, covers, etc. you\u2019ve removed and re-connect the battery.
