Granatelli 1987 Pontiac Grand Prix 8Cyl 5.0L Performance Ignition Wires

Granatelli Motor Sports is known for making performance ignition components. For your 1987 Pontiac Grand Prix with the 5.0L V8 engine, these performance ignition wires are a solid option to consider. They are designed to replace your old, worn-out wires and help ensure a strong spark reaches each cylinder.

These wires feature a silicone jacket, which helps protect the internal conductors from heat and abrasion under the hood. The wire construction is intended to handle the electrical demands of the ignition system, aiming for consistent performance. Replacing old spark plug wires is a common maintenance task that can help restore lost power and improve fuel efficiency if the old ones were degraded.
