The Flame-Thrower HC coil is the perfect match for our Ignitor III rev limiter module. This setup provides a 36-60 percent quicker charge rate but also offers 60,000 volts. A faster charge rate means maximum spark energy is sustained longer and available at a higher engine rpm as well. It's made from a vacuum potted coil body for longer life and its shell is constructed of 6063 T5 aluminum with a black-anodized, corrosion resistant finish. For a more subtle approach to the engine bay, Pertronix also offers their full line of coils in a traditional "canister" design.
