What is the resistance of these spark plug wires?

These Ford Racing spark plug wires feature a spiral-wound suppression core designed for low resistance. This helps minimize spark energy loss, ensuring a strong and consistent spark reaches your engine's cylinders.

Are these wires durable enough for high engine temperatures?

Yes, the wires are constructed with tough silicone insulation and boots that are built to withstand high temperatures. This also helps prevent voltage loss and makes them resistant to common engine bay fluids like fuels, oils, and solvents.

Do these wires come with everything needed for installation?

This set includes the spark plug wires, which are numbered for each cylinder, and a coil wire if your application requires it. It also features 45-degree plug boots for most applications and stainless steel distributor cap terminals.

About this part

Product Details

If you're working on a 1966-1995 Ford Mustang and need a new set of spark plug wires, these 9mm wires from Ford Racing are a solid option. They're built to handle the demands of your engine, ensuring a strong spark gets to each cylinder.

These wires use a spiral-wound suppression core, which keeps resistance low and minimizes spark energy loss. That means you get a more consistent and powerful spark compared to older or less well-built wires. The silicone insulation and boots are tough enough to handle high temperatures and resist voltage loss, helping to prevent misfires. Plus, they're made to stand up to common engine bay fluids like fuels, oils, and solvents, so they'll last a long time. You'll find stainless steel terminals for the distributor cap and a coil wire included where applicable, and each wire is helpfully numbered for easy installation on your specific cylinders. You'll even see the 'Ford Racing' script on them, a nice touch for a performance-oriented part.
