Granatelli 90-93 Chevrolet Pickup/Suburban (Full Size) 8Cyl 7.4L Performance Ignition Wires

This is a set of performance ignition wires from Granatelli Motor Sports, part number 28-1623S. You get the complete set of spark plug wires designed to replace the original ones on your 1990-1993 Chevrolet full-size pickup or Suburban equipped with the 8-cylinder, 7.4-liter engine. These wires are built to carry the spark from your distributor to your spark plugs, ensuring a strong and consistent ignition event for each cylinder.

Granatelli designs these wires to handle the demands of a performance ignition system. They use a high-resistance core wrapped in a durable silicone jacket. This construction helps suppress radio frequency interference, which can cause static on your radio, and also protects the wires from heat and abrasion under the hood. The direct-fit design means they are made to connect to your existing distributor cap and spark plugs without any modifications, making installation straightforward for someone familiar with basic engine work.
