Air filter not included: use it with the filter you already have.<\/li>\n<li><strong>What it fixes:<\/strong> jerking and snatchy throttle at low rpm.<\/li>\n<li><strong>Dyno-tested result:<\/strong> about +4 hp and +6 Nm between 3,000 and 5,500 rpm, with the stock ECU and no remap.<\/li>\n<li><strong>Plug &amp; Play and reversible:<\/strong> it fits the stock airbox with no cutting or drilling.<\/li>\n<\/ul>\n<h2>Low-rpm snatchiness and torque dip on the Desert X: where they come from<\/h2>\n<p>Off-road in slow, technical sections, and on the road in traffic, the stock Desert X tends to have a <strong>snatchy throttle response at low rpm<\/strong>, just when you need it to be smoothest. The dyno also shows a <strong>torque dip between about 4,300 and 5,200 rpm<\/strong>.<\/p>\n<p>The main cause isn't the air filter but the way air gets into the airbox: the stock lid has a very small air inlet, designed mainly to meet European noise homologation limits.<\/p>\n<h2>Why a performance air filter alone isn't enough<\/h2>\n<p>Many Ducati owners start by fitting a <strong>performance air filter for the Desert X<\/strong>. The problem is that the filter sits behind the same stock air inlet: if air can't get into the airbox, a freer-flowing filter changes very little. It's like having a marathon runner's lungs and breathing through a straw.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" width=\"4676\" height=\"4091\" data-attachment-id=\"1399\" data-permalink=\"https:\/\/duegengineering.com\/en\/?attachment_id=1399\" data-orig-file=\"https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?fit=4676%2C4091&amp;ssl=1\" data-orig-size=\"4676,4091\" data-comments-opened=\"1\" data-image-title=\"CONFRONTO ASPIRAZIONE ORIGINALE VS 2G (1)\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?fit=1024%2C896&amp;ssl=1\" class=\"aligncenter wp-image-1399 lazyload\" data-src=\"https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=4676%2C4091&#038;ssl=1\" alt=\"Confronto tra il coperchio airbox originale della Ducati Desert X e il coperchio maggiorato 2G Engineering\" data-srcset=\"https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?w=4676&amp;ssl=1 4676w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=300%2C262&amp;ssl=1 300w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=1024%2C896&amp;ssl=1 1024w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=768%2C672&amp;ssl=1 768w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=1536%2C1344&amp;ssl=1 1536w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=2048%2C1792&amp;ssl=1 2048w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=14%2C12&amp;ssl=1 14w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?resize=600%2C525&amp;ssl=1 600w, https:\/\/i0.wp.com\/duegengineering.com\/wp-content\/uploads\/2026\/09\/CONFRONTO-ASPIRAZIONE-ORIGINALE-VS-2G-1.png?w=3000&amp;ssl=1 3000w\" data-sizes=\"auto\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 4676px; --smush-placeholder-aspect-ratio: 4676\/4091;\" data-original-sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h2>More air, protected filter<\/h2>\n<p>On a bike that also goes off-road, more air shouldn't mean more dust in the engine.
