Granatelli Motor Sports - GM Coil Packs

Granatelli Motor Sports offers high‑performance ignition coil packs designed to deliver stronger, more consistent spark energy for GM engines, helping improve combustion, throttle response, and overall drivability. Ignition coil packs convert the battery’s low voltage into the high voltage needed to fire the spark plugs. When they begin to fail, often shown through misfires, rough idling, reduced fuel economy, or a check‑engine light, it’s a strong sign that replacement is needed. Granatelli’s coil packs are engineered to be compatible with a wide range of GM LS engines, including LS1, LS2, LS3, LS4, LS5, LS6, LS7, LS9, LSA, L92, L99, and L76 platforms, making them a versatile upgrade for many GM performance vehicles. Some of the GM models supported by these LS‑series coil packs include the 1997–2013 Corvettes, 1998–2002 Camaro/Firebird, 2004–2006 GTO, 2010–2015 Camaro, along with a broad lineup of GM trucks that use LS‑based engines
