Granatelli 04-06 Pontiac Grand Prix 6Cyl 3.8L (w/Supercharger) Performance Ignition Wires

If you're working on a 2004-2006 Pontiac Grand Prix with the 3.8L supercharged V6, these Granatelli ignition wires are a solid option for replacing your old, worn-out wires. These wires are built to handle the demands of a supercharged engine, ensuring a strong spark gets to your spark plugs for efficient combustion.

Granatelli uses a high-resistance suppression core with a silicone jacket to protect against heat and abrasion. This construction helps reduce radio frequency interference, which can clean up engine performance and prevent misfires. The wires are designed to fit right, making installation straightforward if you're comfortable working around the engine bay. A consistent spark is key for getting the most out of your supercharged 3.8L, and these wires aim to deliver that reliability.

When replacing your spark plug wires, it's a good idea to inspect your spark plugs and coil packs as well. Ensuring all ignition components are in good shape will help you get the best possible performance from your Grand Prix.
