Why Spark Plug replacement is so important.

Some engine parts are tucked away out of sight, so they are often overlooked. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC M340 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. Should a spark plug fail to do its job, the engine in your GMC M340 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

Good products, great prices, the best people.
