Constructed from corrosion-resistant stainless steel with a carbon fiber finish, it’s built to withstand high under-hood temperatures and resist deformation. The cover installs over standard cone or cylinder style intake filters and ships with the mounting hardware needed for attachment.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this shield reduce intake heat?\u003c\/h3\u003e\n\u003cp\u003eThe shield creates a physical barrier between the hot engine bay and the filter element so the intake draws air that is less affected by radiant heat. That cooler airflow helps the intake system operate more consistently under load without changing your filter or intake plumbing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits around the filter to block direct heat sources and radiant heat.\u003c\/li\u003e\n  \u003cli\u003eStainless steel substrate resists warping from repeated temperature cycles.\u003c\/li\u003e\n  \u003cli\u003eCarbon-finish surface reflects some radiant heat and adds a thermal break.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my air filter and how do I install it?\u003c\/h3\u003e\n\u003cp\u003eThe shield is made for cone or cylindrical intake filters with a neck diameter between 2.5 and 3.5 inches. Installation requires basic hand tools and the included fasteners; a screwdriver is typically all that’s needed, but care should be taken around sharp edges and professional help is recommended if you’re unsure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with cone\/cylinder filters having 2.5\"–3.5\" necks.\u003c\/li\u003e\n  \u003cli\u003eComes with mounting hardware; filter and detailed instructions not included.\u003c\/li\u003e\n  \u003cli\u003eSimple screw-in installation; avoid contact with sharp edges during fitment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and durability features does it offer?\u003c\/h3\u003e\n\u003cp\u003eRULLINE combines a stainless steel base with a carbon-style finish for a balance of strength and style. The materials resist corrosion and maintain shape when exposed to under-hood heat, so the shield remains functional and decorative over time.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-quality stainless steel resists rust and deformation.\u003c\/li\u003e\n  \u003cli\u003eHeat-resistant finish keeps the shield performing under elevated temperatures.\u003c\/li\u003e\n  \u003cli\u003ePrecision-formed edges and mounting points for reliable attachment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDoes the cover change my filter maintenance or airflow?\u003c\/h3\u003e\n\u003cp\u003eThe shield is an external guard and does not replace regular filter maintenance; you should continue cleaning or replacing your filter according to its manufacturer’s schedule. Because it sits outside the filter element, airflow path remains unchanged when installed properly, though localized intake temperatures can be lower.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDoes not alter filter element replacement or cleaning intervals.\u003c\/li\u003e\n  \u003cli\u003eDesigned to preserve original airflow geometry when mounted correctly.\u003c\/li\u003e\n  \u003cli\u003eRecommended periodic checks to ensure fasteners remain tight and edges are undamaged.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Vehicle owners and DIY tuners who use cone or cylindrical aftermarket air filters and want a durable, attractive way to reduce intake heat exposure. It’s suitable for street cars, show builds, and anyone who wants a tidy engine bay with added thermal protection—ideal if your filter neck measures between 2.5 and 3.5 inches and you prefer a carbon\/black aesthetic. Note: professional installation is suggested if you are unfamiliar with intake components; the package includes the shield and hardware but not the air filter or full printed instructions.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What filter neck sizes does this fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits cone or cylinder intake filters with neck diameters from 2.5 to 3.5 inches.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is installation difficult?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Installation is straightforward with a screwdriver and included hardware, but professional help is recommended if unsure.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"North Trail Auto","offers":[{"title":"Default Title","offer_id":48085541355678,"sku":"B086Z65XWY","price":34.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/rulline-front-view-heat-shield.jpg?v=1785872236","url":"https:\/\/northtrailauto.ca\/products\/rulline-heat-shield-for-2-5-3-5-cone-cylinder-air-filters-carbon-black-stainless-steel-low-profile-thermal-protection","provider":"North Trail Auto","version":"1.0","type":"link"}
