Dodge Diplomat Spark Plug

Keeping your Diplomat in top shape is your top priority.

Dodge car, truck, or SUV enthusiasts have become used to a certain level of reliable transport when driving their Diplomat around town. Make no mistake, you didn't buy your Diplomat unless you wanted to buy great performance and great value both rolled up into one automobile. When your Dodge Diplomat was born, it was destined for a person with discerning taste who prioritizes a trusted name in their automobile. Anyone who owns a Dodge knows that when it comes to repairing their car, truck, or SUV only the absolute best replacement parts will do.

Don't go too long without fixing your Spark Plug... here's why.

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 Dodge Diplomat spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. If one of the spark plugs wears out, the engine in your Dodge Diplomat will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

OEM parts, lowest prices, experienced automotive professionals.
