Enrique

Excellent. Rick showed up early and was very friendly and courteous. He was not aggressive in upselling me on additional services which is important to me. He only made recommendations which were actually crucial. He set an appointment for me but told me it was optional and that I could cancel, which I did due to financial restraints at the moment, but I will be booking with him in the near future for the recommended services.

David was great and we were very happy with his service. He showed up 15 minutes early which was very impressive. Was clean and thorough and explained everything in detail. I will definitely have some other services done on our cars and will request David do the work.

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.
