Product Description

The Granatelli 28-0514-CPM Malevolent Series Ignition Coil Pack Set is a high-performance ignition upgrade designed for GM LT-series engines. With an impressive 85 kV output, these coils deliver stronger spark energy compared to many factory units, helping improve combustion efficiency, throttle response, and overall engine performance. This set of eight coil packs is intended to replace stock coils on LT1 and LT4 powered vehicles, offering a plug-and-play solution that fits a wide range of Chevrolet, GMC, and Cadillac LT platforms with minimal effort.

Installation is straightforward using the existing OEM harness connectors, and no modifications are required. Whether you're building a high-performance street car like a Corvette or Camaro, or enhancing power delivery in trucks and SUVs like Silverado, Tahoe, or Yukon models, these coils provide a reliable performance boost. While designed for robust performance applications, these coils are primarily for racing or off-road use where emissions restrictions do not apply; check local regulations before installation if emissions legality is a concern.
