Your cart is empty.Now you can get a stock-look spark plug wire, that performs. We’ve designed our 7mm wires with the same core we use in our 8mm wire. The only difference is the 7mm flat black silicone jacket that hides its performance potential from the naked eye. Get the best of both worlds with state-of-the-art performance and a stock look. These wires will fit most original wire looms. Select a custom tailored set for a great out of the box fit or a universal kit to match your unique engine and wire loom configuration.

I am upgrading the ignition system on my 39 Plymouth pickup truck. The Pentronix electronic module requires resistor wires to operate correctly. Looking throughout the web only uncovered Pentronics as a supplier. These are listed as being used in British vehicles but fit perfectly on my MOPAR engine. These wires in conjunction with the module have increased the spark to the plugs. I measured the spark performance using a digital oscilloscope and observed a significant increase in spark duration. This translates into more energy during the firing cycle.

Supposed to fit 1946 Dodge WC truck. Distributor boots to big. Salvaged old ones to make them fit.

You need to have the proper crimping pliers for these

I highly recommend these wires. When properly installed they give you a nice, custom look and they work flawlessly. Used these on my 49' Ford F3 with an original 226 Flathead engine. Combined with the Pertonix magnetic pickup and coil, it provides a much hotter spark and is more reliable than points/condenser. I installed with my Moroso spark plug wire stripper/crimper and it went together smoothly.
