      Description

      Superb Power Improvement. Maximize the capability of your Chevrolet Silverado’s engine with the GMS Pro Series Coil Packs. These coil-on plugs increase the power to the spark plug by up to 400%. They enable you to gain up to 15 more horsepower when used on normally aspirated trucks, and almost 35 more HP for turbo and nitrous equipped trucks. To top these off, using these on your Silverado gets you a much-improved throttle response while also improving your gas mileage by up to 10%.

      Built to Fit OEM Specs. These coil-on plugs are designed as OEM replacements and have a patented design that will work on your Silverado’s factory fuel injection system while guaranteeing a zero ohm resistance and no RFI/EMI interference. Each coil plug comes with a stainless steel connector cable with stainless steel snap lock plug connectors.

      Installs in Minutes. Installing these coil-on plugs is pretty straightforward and can be done in minutes. Basic hand tools are required for installation. Each set contains 8 coil-on plugs.

      Backed by a 90-Day Warranty. Granatelli Motor Sports (GMS) offers a limited warranty for these Pro Series Coil Packs. For a period of 90 days, these coil-on plugs are protected against defects on both material and workmanship. To read more about the terms and conditions, please refer to the manufacturer’s website.
