Built with a high-conductivity copper winding and a reinforced epoxy-and-engineering-plastic housing, the DG508 is engineered to resist heat and deliver consistent spark performance. Before installation, confirm your vehicle uses the black curved-boot style coil, as this DG508 variant is not compatible with brown or straight-boot coil types.\u003c\/p\u003e\n\n\u003ch3\u003eWill this coil pack fit my 1998–2003 Ford F150?\u003c\/h3\u003e\n\u003cp\u003eYes—when your truck uses the specific black curved boot coil design. The DG508 covers multiple years and engine sizes across Ford trucks and vans, but fitment depends on the boot shape and connector style rather than just model year.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with 1997–2003 F150 5.4L and 1998–2010 F150 4.6L V8 engines when black curved boots are present.\u003c\/li\u003e\n  \u003cli\u003eAlso fits many Crown Victoria, Explorer, E-Series, Excursion, Econoline, and Super Duty applications listed by Marsram.\u003c\/li\u003e\n  \u003cli\u003eNot compatible with brown straight boots or black straight boots—inspect the original coil before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the DG508 differ from OEM or other aftermarket coils?\u003c\/h3\u003e\n\u003cp\u003eThe DG508 emphasizes thermal resistance and electrical conductivity using epoxy resin housing and copper internal windings. That construction helps reduce heat-related failures and supports consistent spark energy across cylinders, but it is still a direct-replacement aftermarket part rather than an OEM-branded unit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExterior: epoxy resin plus high-strength engineering plastic for heat resistance and durability.\u003c\/li\u003e\n  \u003cli\u003eInterior: high-conductivity copper coil to promote fast, reliable ignition response.\u003c\/li\u003e\n  \u003cli\u003eReplaces many factory part numbers (e.g., DG-508, SP479, FD503, GN10164) for straightforward swap-in service.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat benefits can I expect after replacing a failing coil with the Marsram DG508?\u003c\/h3\u003e\n\u003cp\u003eInstalling a properly matched DG508 can eliminate misfires, rough idle, and poor throttle response caused by weak or open coils. While it restores the ignition circuit, overall engine performance also depends on spark plugs, wiring, and fuel\/air systems being in good condition.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eImproved ignition consistency for smoother idle and acceleration when the coil was the fault.\u003c\/li\u003e\n  \u003cli\u003eDurable materials help reduce repeat coil failures from heat exposure.\u003c\/li\u003e\n  \u003cli\u003eSold with a 1-year warranty to help protect against early defects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I confirm compatibility before buying?\u003c\/h3\u003e\n\u003cp\u003eMatch the physical appearance and boot style of your current coil to the DG508 description and cross-check vehicle fitment lists. When in doubt, compare part numbers or contact Marsram with your VIN for confirmation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConfirm the coil has black curved boots—this DG508 only fits that configuration.\u003c\/li\u003e\n  \u003cli\u003eVerify the vehicle model, year, and engine size against the compatibility list provided by the brand.\u003c\/li\u003e\n  \u003cli\u003eUse the parts finder or contact Marsram support with your VIN for an exact match.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The Marsram DG508 is aimed at Ford, Lincoln and Mercury owners, fleet managers, and independent mechanics who need an affordable, durable replacement ignition coil for V8 engines from the late 1990s to mid-2010s. It’s a practical option when the original coil shows misfire codes or visible signs of damage—provided the vehicle uses the black curved-boot coil style. If you aren’t sure about boot shape or part numbers, verify fitment before purchase to ensure a correct, trouble-free swap.\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: Does the DG508 fit brown or straight-boot coils?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The DG508 variant only fits black curved-boot coils and is not compatible with brown or straight-boot styles.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What warranty does Marsram provide for this coil?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Marsram includes a 1-year warranty covering manufacturing defects on this DG508 ignition coil.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Marsram","offers":[{"title":"Default Title","offer_id":48083224133790,"sku":"B09QKHK78M","price":64.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/marsram-dg508-front-view.jpg?v=1785828931","url":"https:\/\/northtrailauto.ca\/products\/marsram-ignition-coil-pack-dg508-for-ford-f150-1998-2003-black-curved-boot-v8-copper-windings-heat-resistant-housing","provider":"North Trail Auto","version":"1.0","type":"link"}
