The PerTronix Coil is outstanding!

I would recomend thesew to anyone hwo asked. Have the black one installed on my original 1935 Model 38 4 door car with 221 Flat Head V8. Have the chrome version installed on my 1938 Chevrolet 2 door Buissness Coup with an inline 6. Both are very reliable. Nethier need a resistor unless your electronic ignition is over 5ohm.

I would not buy this product

Ohmed 4 different coils & none fully reached the required ohms desired by the instructions that came with the Pertronix ignition. Wanted to use the coil recommended to use with the ignition. Pertronix staff said it would work ok but I thought it should reach required ohms listed with the ignition.

matched this coil with a pertronix points eliminator kit in a 57 t-bird to get the reliability of electronic ignition with the stock looking appeal.

Great coil. I'd buy again, but probably won't have to.

Do you need to run the recommended ballast resistor if using the Pertronix ignitor II ignition system on your distributor?
