ENA Ignition Coil Kit for GM V8 — Set of 8 Coils, 8 Platinum Spark Plugs & Red Wire Set for 4.8L/5.3L/6.0L

ENA's complete 8-cylinder ignition kit combines eight square ignition coils, eight platinum spark plugs and a red high-performance wire set designed to restore consistent spark for compatible Chevrolet, GMC and Hummer V8 engines.

This all-in-one replacement ignition kit is engineered as a direct-fit option for a range of GM V8 engines (4.8L, 5.3L and 6.0L model years shown) that use individual coil-on-plug units and standard plug sizing. The components are built to meet OE-style specifications for fit and function, making replacement straightforward for home mechanics and pros. Included parts are cross-referenced to common OE numbers (for example UF271 and 41962) so you can confirm compatibility with your vehicle’s factory parts list.
