Trung was very professional and friendly. He completed the schedule work (replace headlight) quickly and went above and beyond to perform additional check-ups for my car. He also sent me quotes for the next service that I need on the spot. Overall I am very happy with the service.

Did a fine job, even had to go to the auto parts store for the right part. The check engine light went out, so apparently it is fixed. Will use again. Maurie Deming

All about Spark Plug Replacement

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.
