Usually, all you need to do is remove the airbox lid by releasing a few clips or undoing a few screws, and the air filter can be popped right out&mdash;it&rsquo;s that easy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since most air filters are also relatively inexpensive, it&rsquo;s a good idea to change your car&rsquo;s filter regularly. When left unchecked, a dirty air filter can lead to various problems that make your vehicle less efficient and less enjoyable to drive.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does an Engine Air Filter Do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your car&rsquo;s air filter traps contaminants within its fibers to prevent dirt and debris from entering the <a href=\"https:\/\/www.carparts.com\/blog\/car-engine-parts\/\" target=\"_blank\" rel=\"noopener\" aria-label=\"engine\">engine<\/a>. The air filter also promotes clean airflow into the air intake system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The air filter is located downstream from the engine, inside a housing that&rsquo;s attached to the air intake tube. When the engine is running, the pistons move downward in the cylinders, creating a vacuum that pulls air through the air filter and into the engine. That air mixes with fuel and is then ignited, creating the energy to propel your car.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-1024x683.jpg\" alt=\"mechanic checking a dirty engine air filter\" class=\"wp-image-23214\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/dirty-air-filter.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Your car&rsquo;s air filter traps contaminants within its fibers to prevent dirt and debris from entering the engine.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Can Happen When Your Engine Air Filter Is Dirty?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Today&rsquo;s computer-controlled vehicles use sensors to measure the amount of air entering the engine. Because of this, a dirty air filter has less of an effect on engine performance than it did in the past.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The computer can compensate for a dirty air filter&mdash;but only up to a point. When the filter becomes completely clogged (or close to it), there simply isn&rsquo;t enough airflow to keep the engine running properly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An air filter that&rsquo;s seriously neglected can result in several problems, including:<\/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<h3 class=\"wp-block-heading\">Poor Engine Performance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A severely restricted air filter can starve your engine of air, causing performance problems, such as <a href=\"https:\/\/www.carparts.com\/blog\/my-car-wont-accelerate-properly-when-i-push-the-gas-causes\/\" target=\"_blank\" rel=\"noopener\" aria-label=\"poor acceleration\">poor acceleration<\/a> and rough running.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Turbocharged engines, which require an unobstructed air intake to build proper boost pressure, often suffer the most from a clogged air filter. Vintage vehicles with a carburetor are also prone to performance problems caused by a restricted air filter.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-1024x683.jpg\" alt=\"low fuel warning on dashboard\" class=\"wp-image-23217\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/low-fuel.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>A dirty air filter can lead to increased fuel consumption.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Increased Fuel Consumption<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The engine has to work harder than normal to pull air in through a dirty air filter. That rise in energy expenditure often leads to an increase in fuel consumption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Increased Tailpipe Emissions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In extreme cases, a dirty air filter can reduce engine airflow enough to create a rich running condition (too much fuel; not enough air). As a result, the engine will produce a greater amount of tailpipe emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Illuminated Dashboard Warnings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some late-model vehicles are equipped with an air filter life monitor that uses various sensors to detect a dirty air filter. A computer (often referred to as the powertrain control module), receives data from those sensors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the module determines the air filter requires replacement, it turns on a warning light on the dashboard, reminding the driver to replace the air filter. In some extreme cases, a dirty air filter (and the resulting engine performance problems) may also cause the module to turn on the check engine light.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-1024x683.jpg\" alt=\"mechanic holding an air filter\" class=\"wp-image-23216\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/02\/mechanic-holding-an-air-filter.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>If your filter sees severe use, check it every 6 months\/6,000 miles and replace it if it looks dirty.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How Often Should You Change Your Car&rsquo;s Air Filter?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You can approximate how often your car&rsquo;s air filter should be changed by consulting the vehicle manufacturer&rsquo;s service schedule. The information can be found in your owner&rsquo;s manual or supplemental service booklet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But if you regularly drive through a dirty or dusty environment (e.g., dirt roads), you may need to change the filter more frequently than the vehicle manufacturer recommends. If your filter sees severe use, check it every 6 months\/6,000 miles and replace it if it looks dirty. You&rsquo;ll know it&rsquo;s time for replacement when the filter element is dark and allows very little light to pass through.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check out these tutorial videos on how to replace your air filter:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to replace the Air Filter 2009-2014 Ford F150 &#128168;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/QyXAOsVLQ90?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to replace the Air Filter 2009-2018 Dodge RAM 1500 &#128168;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/pxVqaQp_KqE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Need to Replace Your Vehicle&rsquo;s Air Filter?
