Jeep J-300 Spark Plug

Why you drive your J-300.

When your Jeep J-300 left the factory, it was destined for a person with discerning taste who prioritizes a fun driving experience in their automobile. You bought your J-300 because its ruggedness and versatility agreed with your nature; so why would you settle for second rate when it comes to the highest quality auto parts? Your Jeep dealership isn't the only place to find the highest quality parts to repair your J-300. Jeep car, truck, or SUV drivers have grown accustomed to a certain level of adventure when driving their J-300 around town.

Why Spark Plug replacement is so important.

Sometimes the most important performance parts are the smallest, but they aren't considered when there's a performance problem. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your Jeep J-300 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. When one of the spark plugs does not fire when it should, the engine in your Jeep J-300 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
