Show original supplier description
The Granatelli Motor Sports 60KV Street Fighter Series Direct Ignition Coil is engineered to provide a significant boost in ignition performance for GM LS-powered vehicles. This high-output coil delivers a potent 60,000 volts, promoting enhanced combustion efficiency, improved throttle response, and increased horsepower. It serves as a direct, plug-and-play OEM replacement, ensuring an easy installation process that will not void your factory warranty. This ignition coil is compatible with a wide range of GM LS engines, including LS1, LS2, LS3, LS4, LS5, LS6, LS7, LS9, LSA, L92, L99, and L76 variants. Users have reported noticeable improvements in throttle response, idle stability, and overall engine performance. While average gains of 6 to 8hp have been observed on stock vehicles with no other modifications, gains of up to 12hp are possible, with even higher gains of up to 18hp reported on heavily modified, forced induction applications. It is a single-piece unit with a black body, designed to be a direct fit for numerous Chevrolet and GMC models from 2007 through 2018, as well as select Cadillac models. The manufacturer provides a 1-year warranty for this product.
