✓【 GUARANTEED FITMENT IGNITION COIL & SPARK PLUG KIT 】 This complete set includes 4 heavy-duty ignition coils and 4 pre-gapped iridium spark plugs, engineered for 2.5L L4 engines (2002–2006). for Nissan Altima (2002–2006, 2.5L); for Nissan Sentra (2002–2006, 2.5L, with 2002 models requiring Canada or U.S. Emissions); for Nissan X-Trail (2005–2006, 2.5L). Always verify fitment using the compatibility chart. Each ignition coil is marked with cylinder numbers for foolproof installation.
✓【 OEM-EXACT REPLACEMENT FOR NISSAN L4 ENGINES 】 Our ignition coils cross-reference to UF350, 22448-8H310, 5C1395, C1398, 1788319, 22448-8H315, 224488H311, 224488H31, GN10219, and 22448-8H300; iridium spark plugs replace 4505 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 Nissan L4 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–P0304), 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-tipped plugs fire with less voltage while our upgraded coils deliver a hotter spark for smoother idle,sharper throttle response,and a 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. Free torque diagram—just message us. 24-month warranty, no receipt hassles, no hidden clauses. Unsure on fitment? Send year/model—we'll verify within hours. Don't settle for cheap parts.
