What is the main benefit of using performance ignition wires?

Performance ignition wires are designed to deliver a stronger and more consistent spark to your spark plugs. This can lead to improved engine performance, better fuel efficiency, and smoother operation compared to worn-out stock wires.

Are these wires difficult to install?

These wires are designed as a direct replacement for your factory ignition wires. Installation typically involves disconnecting the old wires and connecting the new ones to the correct spark plugs and distributor cap or coil pack. Refer to your vehicle's service manual for specific procedures.

What material is the outer jacket made of?

The outer jacket of these ignition wires is made from silicone. Silicone is known for its good heat resistance, which is beneficial in the demanding environment of an engine bay.

About this part

Product Details

These Granatelli ignition wires use a 7mm silicone jacket with a high-resistance core, designed to handle the electrical demands of your 1986-1991 Chevrolet or GMC truck. They are built to replace your original spark plug wires, helping to ensure a strong spark reaches each cylinder for reliable engine operation. If your truck is running rough, misfiring, or just not feeling as responsive as it used to, a fresh set of performance wires like these can make a noticeable difference.

The silicone construction offers good heat resistance, which is important in the engine bay where temperatures can get high. The high-resistance core is engineered to manage the electrical current effectively, aiming for consistent spark energy. This set fits a wide range of full-size Chevrolet and GMC pickups and vans from the late 80s and early 90s, including popular models like the Chevrolet K1500 and GMC Safari. Replacing old, brittle wires is a straightforward way to maintain your engine's ignition system.
