High-Output Spark Energy for GM LT Performance
```Gen V LT engines use direct injection and increased cylinder pressure to produce impressive factory performance. Modified LT1 and LT4 engines place even greater demand on the ignition system, especially when equipped with additional boost, aggressive tuning, upgraded camshafts, higher compression or nitrous.
Granatelli Pro Series Extreme ignition coils are engineered to provide the increased spark energy required by demanding LT combinations. Whether your vehicle is stock, cammed, supercharged, turbocharged or running nitrous, these high-output coils help provide reliable spark throughout the RPM range.
```Dyno-Proven Performance
```Granatelli reports average gains of 6–8 horsepower on stock engines, gains of up to 12 horsepower over factory coils, and gains of up to 18 horsepower on heavily modified or forced-induction applications. Actual results will vary depending on the vehicle, engine combination, tune, modifications and condition of the existing ignition system.
