PerTronix 3.0 Ohm Coil


While they're the only performance coils that should be used with the PerTronix Ignitor, the 40,000 volt Flame-Thrower canister coils 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. They are oil filled for great heat control, and internally resisted. Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-10). Point Type Distributors: For 240Z's with points, do NOT use this coil with a Ballast Resistor. This Pertronix is a 3 ohm coil, and the 240Z had an original (Coil + Ballast Resistor) resistance of approximately 3 ohms. If you use this coil plus the original Ballast Resistor, you will have around 4.6 ohms of resistance, which will not work properly. If you are using your original Ballast Resistor, choose the 1.5 ohm PerTronix coil instead. Factory Electronic Ignition: 1974 and later Z's with original ignition should use the 1.5 Ohm coil, as opposed to this PerTronix 3.0 Ohm coil, and also should retain the stock ballast resistor. Aftermarket Ignitions: For the PerTronix Ignitor system, PerTronix recommends using this 3.0 Ohm coil, and not using a ballast resistor. If you are using a PerTronix Ignitor, and keeping your ballast resistor, use the 1.5 Ohm coil, instead. For other aftermarket ignition systems, please check with that ignition system manufacturer for whether a 1.5 or 3.0 Ohm coil will work best.
