✓【 GUARANTEED FITMENT IGNITION COIL KIT 】 This complete set includes 8 heavy-duty ignition coils, engineered for 4.8L, 5.3L, 6.0L & 6.2L V8 engines (2005–2014). for Chevrolet Silverado/Suburban/Tahoe/Avalanche/Express/Corvette; for GMC Yukon/Sierra/Savana; for Hummer H3 (2008–2009); for Pontiac Grand Prix (2005–2008). 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 UF414, CUF414, C1512, D514A, 5C1555, E894, 52-1820, IC534, 12573190, UF-414, GN10165, 12570616, 12611424, and 1788407. Built strictly to factory dwell time, heat range, and connector specs—no check-engine lights, no reflash needed.
✓【 WHY REPLACE YOUR IGNITION COILS 】 On V8 engines, under-hood heat often exceeds 300°F, degrading ignition coils over time. Replacing your ignition coils 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 output under high loads. Built with silicon steel cores, high-pressure rubber protective sleeves, Japanese high-temp epoxy, and German copper windings, our coils resist cracking, voltage leaks, and interference—delivering quicker ignition, improved spark plug power, and optimized fuel economy (+1–2 MPG) with a service life over 80,000 kilometers.
✓【 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.
