Since spark plugs are regularly exposed to a lot of heat, they will eventually wear out and need to be replaced. However, their lifespan isn&rsquo;t set in stone and can vary due to several factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What&rsquo;s the Replacement Interval of Spark Plugs?<\/h2>\n\n\n\n<p>In the 1960s and &lsquo;70s, spark plug intervals were about 12,000 miles between &ldquo;tune ups,&rdquo; which included points and condenser in the distributor, along with timing and carburetor adjustments.<\/p>\n\n\n\n<p>But by about 1980, spark plug replacement intervals had increased dramatically, presumably because electronic ignition created a spark that was so much hotter than the old points-and-condenser systems.<\/p>\n\n\n\n<p>After about 1980, which typically called for spark plug replacement at about 30,000 miles, it wasn&rsquo;t unusual to find that a car owner had driven over 100,000 miles without replacing the spark plugs and yet had no issues. <strong>As model years came and went, spark plug replacement intervals increased to 100,000 miles<\/strong>.<\/p>\n\n\n\n<p>A spark plug&rsquo;s lifespan depends on its type. Spark plugs vary according to the different metals used in their electrode tips.<\/p>\n\n\n\n<p>Ordinary spark plugs made from copper and nickel should last<strong> 30,000 to 50,000 miles but may last as much as twice that many miles<\/strong>. Spark plugs made from platinum and iridium last longer. Platinum spark plugs typically last for <strong>60,000 miles<\/strong>, while iridium spark plugs can last anywhere between <strong>80,000 and 100,000 miles<\/strong>. But as mentioned, spark plugs may last as much as twice that many miles.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"750\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer-1024x750.jpg\" alt=\"spark plug replacement on a 2008 ford explorer\" class=\"wp-image-82535\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer-1024x750.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer-300x220.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer-768x563.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer-150x110.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/spark-plug-replacement-on-a-2008-ford-explorer.jpg 1048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">The spark plug pictured in the photo was replaced as part of a set during a routine checkup on this 2008 Ford Explorer at 238,000 miles.

The electrode is where the spark is generated, from which it jumps to a protruding hook. Other factors can accelerate the rate at which your vehicle&rsquo;s spark plug wears. As a result, the manufacturer&rsquo;s replacement interval might not match the rate at which your spark plug is wearing out.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"471\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/types-of-ignition-systems-affect-spark-plug-wear.jpg\" alt=\"types of ignition systems affect spark plug wear\" class=\"wp-image-82536\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/types-of-ignition-systems-affect-spark-plug-wear.jpg 722w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/types-of-ignition-systems-affect-spark-plug-wear-300x196.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/types-of-ignition-systems-affect-spark-plug-wear-150x98.jpg 150w\" sizes=\"(max-width: 722px) 100vw, 722px\"><figcaption class=\"wp-element-caption\">Different types of ignition systems will also affect spark plug wear and spark plug change intervals. The two spark plugs in the photo were fired by the same coil over many tens of thousands of miles on a coil pack system where the coils are fired in pairs. One of the spark plugs will wear the center electrode more and the companion plug will wear the ground (side) electrode more because of the way the spark travels on each plug. | Image Source: Richard McCuistian.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Overheating Damage<\/h3>\n\n\n\n<p>Frequently driving your engine at its limit, such as driving your car on the track, can overheat spark plugs and cause the electrode to wear faster.

The washer or the beveled seat on spark plugs is designed to carry heat out of the plug and into the cylinder head. Plugs won&rsquo;t always fail this way when left loose, but this one did. It doesn&rsquo;t happen a lot, but an intake valve leak can also cause spark plugs to be destroyed by heat very rapidly like this. | Image Source: Richard McCuistian.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Oil Contamination<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"829\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/oil-clogged-sparks-plug-tip.jpg\" alt=\"oil clogged sparks plug tip\" class=\"wp-image-82542\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/oil-clogged-sparks-plug-tip.jpg 900w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/oil-clogged-sparks-plug-tip-300x276.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/oil-clogged-sparks-plug-tip-768x707.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/04\/oil-clogged-sparks-plug-tip-150x138.jpg 150w\" sizes=\"(max-width: 900px) 100vw, 900px\"><figcaption class=\"wp-element-caption\">Sometimes, oil can clog the spark plug&rsquo;s tip.

If you know your way around your vehicle&rsquo;s engine, here are a few things you can do to maximize your spark plug&rsquo;s lifespan:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Regularly Inspect the Electrodes<\/h3>\n\n\n\n<p>The spark plug&rsquo;s electrodes typically fail when they become clogged with soot, oil, or rust. Pulling them out for inspection and cleaning them can help them last longer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pick Good Spark Plugs<\/h3>\n\n\n\n<p>When it&rsquo;s time to replace your spark plugs, pick the ones that are recommended by the manufacturer, which can be found in the owner&rsquo;s manual. You can also ask your mechanic if it&rsquo;s recommended to fit your vehicle with spark plugs that have longer lifespans.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Maintain the Gap<\/h3>\n\n\n\n<p>If a spark plug gap is too close, it can cause a random idle misfire that may not even be noticeable at higher rpm. If the gap is too wide, it can cause misfires under high rpm load.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<p>You should <a href=\"https:\/\/www.carparts.com\/blog\/how-to-gap-a-spark-plug\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"maintain the gap\">maintain the gap<\/a> as prescribed by your owner&rsquo;s manual. There are also tools that are made specifically for checking and maintaining the spark plug&rsquo;s gap. Setting the gap a few thousands wider than a narrow factory spec will typically help with idle quality and starting. For example, if the spark plug gap calls for .042 to .046, you can set the plug gap at .050 and the engine will idle better and start better. But if the called-for gap is .050 or more, just use the factory spec.<\/p>\n\n\n\n<p>Always check the spark plug gap on replacement plugs even if they&rsquo;re supposed to be pre-gapped because you don&rsquo;t know how they were handled while they were still in the box. Keep in mind that all the plugs need to be gapped the same.<\/p>\n\n\n\n<p>Some tools for setting spark plug gaps may require more advanced automotive DIY skills. That said, if you follow these maintenance tips, then your spark plugs have a good chance of reaching their intended lifespan.<\/p>\n\n\n\n<script type=\"application\/ld+json\">\n    {\n        \"@context\": \"https:\/\/schema.org\",\n        \"@type\": \"QAPage\",\n        \"mainEntity\": {\n            \"@type\": \"Question\",\n            \"name\": \"How Long Is the Lifespan of Spark Plugs?\",\n            \"text\": \"How Long Is the Lifespan of Spark Plugs?\",\n            \"answerCount\": 1,\n            \"upvoteCount\": 0,\n            \"dateCreated\": \"2023-03-09T10:13:44Z\",\n            \"dateModified\": \"2023-04-18T04:46:25Z\",\n            \"author\": {\n                \"@type\": \"Person\",\n                \"name\": \"A user\"\n            },\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"Ordinary spark plugs made from copper and nickel should last 30,000 to 50,000 miles but may last as much as twice that many miles.
