✓【 GUARANTEED FITMENT IGNITION COIL KIT 】 This complete set includes 8 heavy-duty ignition coils, engineered for 5.7L, 7.4L & 8.1L V8 engines (1997–2005). for Cadillac CTS (2004–2005, 5.7L); for Chevrolet Avalanche/Suburban/Silverado/Express/Corvette/Camaro; for GMC Yukon/Savana/Sierra; for Pontiac Firebird/GTO. 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 UF192, D580, 5C1078, E247, 52-1573, IC334, 12556450, 12558948, UF-192, GN10374, and C-639. 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 high-grade materials for heat resistance, abrasion resistance, and corrosion resistance, our coils resist cracking, voltage leaks, and interference—delivering quicker ignition, improved spark plug power, and 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.
