Spark plugs are components of your GMC Envoy designed to provide the sparks which ignite the air-and-fuel mixture in your combustion chambers. Spark plugs are attached to your distributor’s terminals using insulated ignition wires. These plugs are composed of various parts, including terminals, resistors, ribs, insulators, central electrodes, and so on. And of course, there are different variations in the construction, especially when it comes to ground electrodes. Some spark plugs may feature two, three, or four electrodes. Most of the time, spark plug electrodes are manufactured from such materials as platinum, silver, iridium, copper, and others.
If your auto’s spark plugs are not checked during regular maintenance services and changed whenever necessary, then they can cause bigger problems with your engine. Some of the biggest tell-tale signs of worn spark plugs are misfiring, surging, greater fuel consumption, poor acceleration, rough idling, smoke in the exhaust, and so on. And of course, a brand-new set of GMC Envoy spark plugs will surely become a cure for any and all of the aforementioned issues. A brand-new set of spark plugs can last for hundreds of thousands of miles.
