Theodore was a star - very polite, called ahead when he was running behind due to unforeseen events outside his control, and did the work efficiently and quickly, much sooner than I expected. Absolutely professional, and I'd hire him again.

Casey changed valve cover gaskets on my 2001 Subaru six cylinder engine. A very time consuming job. He arrived promptly and worked diligently to get the job done. I recommend him for any work that is needed to be done. My job was something I did not want to do myself and Casey performed better than I could have expected. Will use him again if the need arises.

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.
