Jeep Cherokee Spark Plugs

How many times have you replaced the spark plugs of your Jeep Cherokee ? Indeed, it is one of the most common service operations in vehicles, but few of us actually know the real role played by spark plugs. Besides providing the spark that ultimately ignites the air-fuel mixture in the combustion chambers of the cylinders, spark plugs play another, less known role, transferring part of heat generated during combustion to the cooling system . Standard spark plugs feature a coating of porcelain wrapping a central electrode made of copper surrounded by nickel alloy. Design type, geometry of the insulation and materials define the characteristics of spark plugs, making them more or less suitable for a certain engine.

There are so many types of spark plugs. Cold plugs, most suitable for high performance engines, have less insulation and dissipate more heat; hot plugs, more common on standard engines, feature more insulation to maintain higher temperature, allowing for reducing carbon deposits and lengthening the lifespan of spark plugs. In our online shop, we carry a vast choice of both hot and cold Jeep Cherokee spark plugs skillfully designed to provide timely sparks and effective heat transfer, improving the performance of your off-roader.
