✓【 GUARANTEED FITMENT IGNITION COIL & SPARK PLUG KIT 】 This complete set includes 8 heavy-duty ignition coils and 8 pre-gapped iridium spark plugs, engineered for 5.6L V8 engines (2004–2006). for INFINITI QX56 (2004–2006, 5.6L); for Nissan Armada (2005–2006, 5.6L), TITAN (2004–2006, 5.6L), Pathfinder (2004, 5.6L). Always verify fitment using the compatibility chart. Each ignition coil is marked with cylinder numbers for foolproof installation.
✓【 OEM-EXACT REPLACEMENT FOR V8 ENGINES 】 Our ignition coils cross-reference to UF510, 5C1482, 1788335, 6734021, C719, CUF510, GN10243, 224487S015, C1483, IGC0004, E1010, 52-1802, and IC590; iridium spark plugs replace 6240, PLFR5A-11, and NGK/Denso equivalents. Built strictly to factory dwell time, heat range, and connector specs—no check-engine lights, no reflash needed.
✓【 WHY REPLACE YOUR IGNITION COILS & PLUGS TOGETHER 】 On V8 engines, under-hood heat often exceeds 300°F, degrading ignition coils and widening plug gaps over time. Replacing both together restores the entire ignition path—eliminating misfire codes (P0300–P0308), rough idle, hesitation, and cold-start stumbles. It's a complete cure, not a band-aid.
✓【INSTANT PERFORMANCE GAINS & BETTER FUEL ECONOMY 】 Upgrade your drive with reliable ignition coils that maintain stable voltage under high loads.Built with high heat–resistant materials to withstand extreme under-hood stress,our coil packs deliver quicker ignition and improved spark plug power.Our iridium plugs fire with less voltage while our upgraded coils deliver a spark for smoother idle,sharper throttle response,and a noticeably quieter engine—with optimized fuel economy (+1–2 MPG).
✓【 STOP WORRYING ABOUT PREMATURE FAILURE 】 Built for extreme heat & vibration, this ignition coil resists cracking & internal shorting better than others. 15-min install with 10mm & 5/8" sockets; torque to 18 ft-lbs.
