While its the perfect coil to go with the pertronix ignitor breaker less ignition, our 40,000 volt flame-thrower canister coil can benefit virtually any distributor type inductive system. Its higher voltage allows larger spark plug gaps for added power, smoother response and better fuel economy. These coils are internally resisted so they are compatible with many ignition systems. 1.5 ohms coil, 6 overall height.
