Product Details

✓【 GUARANTEED FITMENT IGNITION COIL & SPARK PLUG KIT 】 This complete set includes 5 heavy-duty ignition coils and 5 pre-gapped iridium spark plugs, engineered for 3.5L & 3.7L L5 engines (2004–2008). for Chevrolet Colorado (2004–2006); for GMC Canyon (2004–2006); for Hummer H3 (2006); for Isuzu i-350 (2006) / i-370 (2007–2008). Always verify fitment using the compatibility chart. Each ignition coil is marked with cylinder numbers for foolproof installation.

✓【 OEM-EXACT REPLACEMENT FOR L5 ENGINES 】 Our ignition coils cross-reference to UF303, 12568062, 5C1392, E255, 52-1743, GN10114, IC414, 19300921, 8-12568-062-0, 48844, 8Q5, 1788390, C642, and C1395; iridium spark plugs replace 5019, LTR5GP, 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 L5 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–P0305), rough idle, hesitation, and cold-start stumbles. It's a complete cure, not a band-aid.

✓【INSTANT PERFORMANCE GAINS & BETTER FUEL ECONOMY 】 Upgrade with reliable coils that hold stable voltage under high loads. Built with silicon steel, German copper, Japanese epoxy, and rubber sleeves to resist cracks, shorts, and failure. Our iridium plugs feature CNC-machined shells and ceramic insulators for precise spark. Enjoy smoother idle, sharper throttle, quieter engine, and +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. Add to Cart and drive with confidence.
