Granatelli 99-10 Ford Mustang 8Cyl 4.6L (4V Coil On Plug) MPG Plus Ignition Wires

You're getting a set of Granatelli MPG Plus ignition wires, part number 38-1705MPG. These wires are designed to replace your old, worn-out spark plug wires on a wide range of Ford, Lincoln, and Mercury vehicles from the late 90s through the mid-2010s. Think of vehicles like the Ford F-150, Mustang, Crown Victoria, or the Lincoln Navigator – these wires are built to fit them.

What makes these wires stand out is their construction, aimed at improving the spark energy that reaches your spark plugs. They use a special resistance wire core that helps reduce radio frequency interference, which is good for keeping your electronics running smoothly, and also helps deliver a more consistent spark. This improved spark can lead to better combustion, potentially giving you a bit more pep and improved fuel efficiency. They're a solid option if your current wires are showing signs of age, like misfires or rough idling.

When you're installing these, you'll find they're made to fit right into the factory locations, making the job straightforward. Just be sure to route them carefully to avoid any kinks or rubbing against hot engine components. It's a good idea to replace them in sets to ensure consistent performance across all your cylinders.
