What is the main benefit of using performance ignition wires?

Performance ignition wires are designed to deliver a stronger, more consistent spark to your spark plugs. This improved spark helps ensure more complete fuel combustion, which can lead to a smoother running engine and better overall performance.

Will these wires cause radio static?

These Granatelli wires feature a spiral-wound conductor core designed to suppress radio frequency interference (RFI). This helps minimize static on your radio and ensures a clean spark signal reaches the spark plugs.

Do these wires come with new spark plugs?

This product is for the ignition wire set only. Spark plugs are sold separately and should be checked for condition and replaced if necessary during the same service.

Product Details

If you've got a 1990-1993 full-size Chevrolet pickup or Suburban with the 8-cylinder, 7.4-liter engine, these performance ignition wires from Granatelli Motor Sports are a solid option for your tune-up. These wires are built to carry a strong spark from the distributor to the spark plugs, which is crucial for getting the most out of your engine. A good spark means better fuel combustion, leading to a smoother running engine and potentially improved throttle response.

Granatelli uses a spiral-wound conductor core in these wires, which helps to suppress radio frequency interference (RFI). This means you're less likely to experience static on your radio and, more importantly, the spark signal reaching your plugs stays clean and strong. The wires are also designed to handle the heat and vibration found under the hood, ensuring they last. They're a direct fit for the specified trucks and Suburbans, making installation straightforward if you're replacing your old, worn-out wires.
