What could be left to engineer into a spark plug wire? Well, if you're a member of the team that designs Nology spark plug wires, you figured quite a bit. Nology spark plug wires, rather than utilizing a thicker jacket or lower-resistance core, actually have a capacitor built right in. It's an interesting idea, unique to Nology spark plug wires, that allows 300 times the spark energy to be transmitted to the plug when compared with conventional ignition wires. So how do these Nology ignition wires work? Well, spark is stored in the Nology spark plug wires via their capacitors. There's one capacitor for each Nology spark plug wire. When the voltage is high enough to jump the spark gap (at the moment of ignition), the regular spark is sent through the Nology spark plug wires, but the built-up charge in the capacitors is added and sent through the Nology spark plug wires. That means you get a huge spark when you use Nology spark plug wires. Nology spark plug wires are custom-made for a wide variety of cars and trucks, so you can find Nology spark plug wires for your ride. And when you buy your Nology spark plug wires here, you know you got the best price on the web.
