Product Details
When you're changing spark plugs, it's a good time to inspect and replace your ignition coil boots. These NGK Coil on Plug Boots are built to match the original equipment design and fit for a wide range of GM SUVs and trucks, including models like the Buick Rainier, GMC Envoy, and Chevrolet Trailblazer. They bridge the gap between the ignition coil and the spark plug, and a worn-out boot can lead to ignition problems like flashover.
NGK uses premium silicone for these boots, ensuring they hold up well over time. They also include any necessary internal springs and ferrite resistors, which help suppress RFI noise and maintain superior performance. Replacing these boots along with your spark plugs is a smart move to ensure your ignition system stays reliable and prevents future issues.
