What is the main benefit of performance ignition wires?

Performance ignition wires are designed to deliver a stronger, more consistent spark to your engine's spark plugs. This can lead to improved throttle response, smoother idling, and potentially better fuel efficiency compared to worn-out stock wires.

What materials are these Granatelli wires made from?

These wires feature a high-resistance core for efficient spark transfer and a silicone outer jacket. The silicone provides protection against engine heat and physical abrasion, helping them last longer.

Do these wires come with everything needed for installation?

This set includes the ignition wires themselves. It's always a good idea to inspect your spark plugs and distributor cap/rotor when replacing wires, as these components also wear out and can affect ignition performance.

About this part

Product Details

If you're looking to get the most out of your 3.8L V6 engine, especially in your 1986-1987 Buick, Oldsmobile, or 1987 Pontiac Bonneville, a good set of ignition wires makes a real difference. These Granatelli performance wires are built to handle the demands of a tuned engine, ensuring a strong spark reaches each cylinder for consistent power and smoother running.

Granatelli uses a high-resistance core wire wrapped in a durable silicone jacket. This construction helps suppress radio frequency interference, which can cause static on your radio, while also protecting the wires from heat and abrasion under the hood. The wires are designed to fit right, making installation straightforward for most DIY mechanics. You'll notice improved throttle response and a more stable idle once these are installed.

This set is designed for a range of GM vehicles from the mid-80s, including popular models like the Buick LeSabre and Oldsmobile Delta 88. They are a solid option when it's time to replace old, worn-out wires and you want a bit more performance than stock.
