Hummer H3 Spark Plug

Keeping your H3 in top shape is your top priority.

While it may not be difficult to find replacement parts for Hummer vehicles, these days the necessity for nothing but the highest quality are required to repair your automobile. Anyone who owns a Hummer knows that when it comes to repairing their vehicle only the highest quality replacement parts will do. The vehicle in your driveway symbolizes the best in class compared to all the other vehicles these days. Your Hummer dealership isn't the only place to locate the highest quality replacement parts for your H3.

Why Spark Plug replacement is so important.

Some engine parts are tucked away out of sight, so they can be forgotten about when performing regular maintenance. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Hummer H3 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 Hummer H3 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
