Gen V GM Coils, 2014 And Up, Black, Square 8 Pack Performance Coils For 2014 And Up GM Gen V Direct Injected Engines ACCEL

The Accel Square Coil Packs are meticulously engineered to generate a significantly hotter and more powerful spark compared to conventional ignition coils, leading to more complete and efficient fuel combustion within the engine cylinders. This enhanced spark energy improves overall combustion efficiency, resulting in a noticeable enhancement in throttle response, quicker acceleration, and a more immediate feeling of power. These coil packs also contribute to maintaining stable and smooth engine idle, minimizing rough idling, vibrations, or engine stalling, particularly under varying engine loads or when the vehicle is stationary.
