What is the main benefit of these MPG Plus ignition wires?

Do these wires come with new spark plugs?

Product Details

If you're working on a 2002-2007 Chevrolet Trailblazer, GMC Envoy, or Buick Rainier with the 4.2L 6-cylinder engine, these Granatelli MPG Plus ignition wires are a solid choice for replacing your old, worn-out set. These wires are designed to carry the spark from your ignition coils to your spark plugs, and a healthy set ensures a strong, consistent spark for efficient combustion.

Granatelli builds these wires with a focus on reliable spark delivery. They use a high-resistance conductor core wrapped in a durable silicone jacket. This construction helps suppress radio frequency interference, which can clean up engine performance and potentially improve fuel economy. The wires are made to fit right, connecting securely to your coil packs and spark plugs, so you can expect a straightforward installation when it's time to swap them out.

This set is designed for vehicles using a coil-on-plug ignition system, meaning each spark plug has its own coil. It's a good idea to replace all your spark plug wires at once to ensure consistent performance across all cylinders. If your vehicle is running rough, misfiring, or you're just looking to refresh your ignition system, this set from Granatelli is a well-built option.
