This 8-piece set is built for owners who are dealing with high-mileage ignition maintenance, cylinder misfire symptoms, rough idle, hesitation under load, or uneven startup behavior. Before ordering, match the year, model, engine, OE reference, connector shape, mounting point, coil body, and boot length with the original coil.\u003c\/p\u003e\n\u003ch3\u003eScenario-Based Solutions\u003c\/h3\u003e\n\u003ch4\u003eRough Idle or Shaky Cold Start\u003c\/h4\u003e\n\u003cp\u003eIf the engine starts but shakes at idle, feels uneven at stoplights, or shows a cylinder-specific misfire code, a weak ignition coil may be part of the problem. Replacing aged DG508-style coils can help support more consistent spark delivery after the spark plugs, connectors, and wiring have been checked.\u003c\/p\u003e\n\u003ch4\u003eHesitation When Accelerating, Towing, or Climbing Hills\u003c\/h4\u003e\n\u003cp\u003eOlder Ford truck and SUV engines may feel acceptable at light throttle but hesitate when the engine is under load. A weak coil can show up more clearly during towing, uphill driving, passing, or highway merging. This full 8-piece set is useful when you want to refresh the coil-on-plug system across all cylinders instead of replacing only one coil at a time.\u003c\/p\u003e\n\u003ch4\u003eHigh-Mileage Ignition Maintenance\u003c\/h4\u003e\n\u003cp\u003eWhen one original coil has failed, the remaining coils may be the same age and exposed to the same heat cycles. Replacing all 8 coils during the same service can make maintenance more consistent across the engine bank, especially on older F-150, Expedition, Explorer, Mustang, Crown Victoria, Navigator, and Grand Marquis service groups listed below.\u003c\/p\u003e\n\u003ch4\u003eHeat, Moisture, and Worn Boot Concerns\u003c\/h4\u003e\n\u003cp\u003eIgnition coils work in a hot engine bay and may be affected by worn boots, loose connectors, oil around the plug well, moisture, or damaged wiring. During installation, inspect the spark plugs, coil boots, connectors, and mounting area so the new coils are not stressed by an unresolved issue.\u003c\/p\u003e\n\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel \/ Years\u003c\/th\u003e\n\u003cth\u003eFitment Notes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eF-150 1997-2010; F-250 1997-1999; Explorer 2002-2005; Expedition 1997-2004; Mustang 1999-2004; Crown Victoria 1998-2011\u003c\/td\u003e\n\u003ctd\u003eListed Ford service groups using a matching DG508-style ignition coil design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLincoln\u003c\/td\u003e\n\u003ctd\u003eNavigator 1998-1999\u003c\/td\u003e\n\u003ctd\u003eConfirm exact engine, connector shape, and OE reference before ordering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMercury\u003c\/td\u003e\n\u003ctd\u003eGrand Marquis 1998-2011\u003c\/td\u003e\n\u003ctd\u003eListed Mercury service group using a matching DG508-style coil design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eNecessary Product Parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart type: ignition coil pack \/ coil-on-plug replacement.\u003c\/li\u003e\n\u003cli\u003eQuantity: 8 ignition coil packs.\u003c\/li\u003e\n\u003cli\u003ePrimary reference: DG508.\u003c\/li\u003e\n\u003cli\u003eOther references: DG481, DG491, E213, E262, E409, F523, 521761, 88921369, 1L2U12029AA, 1L2Z12029AA, 1L5Z12029AA, 3W7E12A366AA, 3W7Z12029AA, 5C1412, FD-493, FD-503, FD507, IC369, IC62, F7TU12029BA, F7TU12A366AB, F7TZ12029AB, F7TZ12029CA, F7TZ12029CC.\u003c\/li\u003e\n\u003cli\u003eReplacement style: OE-style aftermarket replacement part, not a factory-branded Ford, Lincoln, or Mercury part.\u003c\/li\u003e\n\u003cli\u003eIncluded parts: ignition coils only; spark plugs are not included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat to Check Before Ordering\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm the year, make, model, trim, and engine before purchase.\u003c\/li\u003e\n\u003cli\u003eCompare the OE or reference number on the old coil when available.\u003c\/li\u003e\n\u003cli\u003eMatch the connector shape, mounting location, coil body, and boot length.\u003c\/li\u003e\n\u003cli\u003eRead misfire codes such as P0301-P0308 when the check engine light is on.\u003c\/li\u003e\n\u003cli\u003eInspect spark plugs first.
