Product Details
✓【 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 2.0L & 2.5L L4 engines (2013–2020). for Mazda 3 (2014–2020), 6 (2014–2020), CX-3 (2016–2020), CX-5 (2013–2020), MX-5 Miata (2016–2018). Always verify fitment using the compatibility chart. Each ignition coil is marked with cylinder numbers for foolproof installation.
✓【 OEM-EXACT REPLACEMENT FOR MAZDA L4 ENGINES 】 Our ignition coils cross-reference to UF656, PE0118100A, C1837, 5C1894, GN10625, and C-857; iridium spark plugs replace 93501, LKAR7BIX-11S, 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 Mazda 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.
