Excellent! Was prompt, very knowledgable and professional. Even went the extra step and went to pick up and fix my issue when I had only booked him for a diagnosis. Did a second quote, paid, done. Very efficient and friendly. Will 100% use him again for my future car service needs.

Kyle was professional and quick, and I appreciated the information he provided on the issue with my car. Although he did call to let me know his previous appointment ran late, he stated his ETA would be 20 minutes but ended up being an hour. My 10:00 appointment time ended up starting well after 11.

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.
