Granatelli 83-90 Ford Mustang 4Cyl 2.3L Performance Ignition Wires

If you're looking to get the most out of your 4-cylinder engine, especially in a classic Ford or Mercury vehicle, a good set of spark plug wires is essential. These Granatelli ignition wires are built to replace the stock wires on a wide range of vehicles, including the Ford Mustang, Aerostar, and Ranger, as well as Mercury Capri and Merkur XR4Ti models from the late 70s through the early 90s. They help ensure that a strong, consistent spark reaches your spark plugs, which is crucial for efficient combustion and smooth engine operation.

Granatelli uses a silicone jacket over a suppressed copper core to build these wires. The silicone helps protect the wires from heat and abrasion under the hood, while the suppressed copper core is designed to reduce radio frequency interference, so you don't get static on your radio. This construction aims to provide a reliable connection and improved spark energy compared to worn-out original wires. They fit right into the factory locations, making the installation straightforward for most DIYers.

When you're replacing spark plug wires, it's often a good idea to inspect your spark plugs and distributor cap or coil packs at the same time. Making sure all the components in your ignition system are in good shape will help you get the best results from your new wires.
