Jeep Commander Spark Plugs

A spark plug is what ignites fuel inside your Jeep Commander’s engine. It's quite an important job that influences a range of critical parameters, from the smoothness of vehicle start to fuel efficiency. But because of the extreme conditions that these small parts operate under, their lifespan can be pretty short. Depending on a number of factors such as the quality of fuel, overall condition of the engine and the quality of spark plugs themselves, it ranges hugely. Yet, when it comes to the end of spark plugs' service life, the symptoms are pretty common – rough and uneven idling, erratic acceleration, and loss of power.

Having noticed that, you shouldn’t wait for long before buying the replacements. The longer your engine runs on five (seven) cylinders, the more problems you can expect in the future. Unburnt fuel wreaks havoc on the exhaust system and especially the catalytic converter – hydrocarbons accumulate on its surfaces, gradually clogging up the system and restricting the exhaust flow. This ultimately causes catalytic converter failure, and the replacement is pricey. In case of spark plugs, going for high-quality parts is reasonable. Our Jeep Commander speak plugs will ensure proper engine performance while serving longer.
