The 2021 Jeep Grand Cherokee is a mid-size SUV that provides a comfortable on-road ride and good off-road performance. It is an excellent choice not only for trips off the paved road but also for daily cruising in town or long travels on the highway. But if you want to get maximum efficiency from your SUV, you should perform regular servicing to ensure that everything under the hood is in top shape. Replacing spark plugs is one of the most common maintenance procedures.
These components are responsible for delivering a spark to the combustion chamber to ignite the air-fuel mixture. Spark plugs are offered in several designs and materials, depending on specific requirements. Due to a harsh working environment, standard nickel plugs usually need to be replaced more frequently than their iridium counterparts. Poor acceleration and fuel economy, rough idling, and engine misfiring are the common symptoms of malfunctioning plugs.
