Description
Excellent Performance Improvement. Have your Chevrolet Silverado running at the maximum performance with the GMS Pro Series Coil Packs. These coil-on plugs give you an additional 15 horsepower when used on normally aspirated trucks, and up to 35 HP gains for turbo and nitrous trucks. In addition, these plugs deliver an almost 400% increased power to the spark plug when compared to stock. Topping all these off, installing these on your truck will give you a better throttle response while boosting your gas mileage to up to 10%.
Built to Satisfy OEM Specs. Designed as an OEM replacement, each coil pack features a stainless steel connector cable with stainless steel snap lock plug connectors. It uses a patented design that is compatible for use with your Silverado's stock fuel injection system. This upgrade ensures a zero ohm resistance and is guaranteed to have no RFI/EMI interference.
Quick Installation. These coil-on plugs are designed for a straightforward installation and can be done in less than an hour. Only basic hand tools are needed for installation. Each set comes with 8 plugs and 8 high-performance ignition wires.
Covered by a 90-Day Warranty. These Pro Series Coil Packs are backed by a limited warranty. For a period of 90 days, Granatelli Motor Sports (GMS) will cover factory flaws detected on both material and workmanship. Read more about the full warranty policy from the manufacturer's website.
Application. GMS Pro Series Coil Packs with High-Performance Ignition Wires will work perfectly on all 1999-2004 Chevrolet Silverado 1500 models equipped with the 4.8L or 5.3L engine.
