Regardless if you are already experiencing issues or just want to replace the spark plugs before they happen, let us take care of it. Our technicians will check out your vehicle and provide you with options for the best fix to keep you on the road.


How Do Spark Plugs Work?

What Are Spark Plugs?

The spark plug is a component that delivers a small spark of electricity to ignite the fuel and air mixture in a normal internal combustion engine. A gasoline engine won’t run or start without spark plugs. We make sure to use the specified spark plug gap, so the engine performs its absolute best. A gapping tool makes an exact measurement (somewhere between .020 and .040 of an inch) to ensure the spark plug gap is correct. This is only applicable to gasoline engines because there is no such thing as diesel spark plugs. Instead of spark plugs, diesel engines use glow plugs.

So, come on in and change out those spark plugs and see what you’ve been missing.
