Our highly-trained technicians will inspect your vehicle and provide you with options for the best fix to keep you on the road.


Spark Plugs, What Are They?

How Do Spark Plugs Work?

The spark plug is a part that delivers electricity to ignite the fuel and air mixture in the standard internal combustion engine. An engine can’t run or start without spark plugs. To ensure the engine performs its best, we use the right spark plug gap. A gapping tool is used to make a precise measurement to ensure the spark plug gap is correct. This is only applicable on gas engines because diesel engines don’t use spark plugs. Instead of spark plugs, diesel engines use glow plugs.
