Engine Tune-Up Parts

The engine components evaluated during an engine tune-up service will vary depending on your vehicle’s condition, mileage, and manufacture’s recommendations. For some vehicles an engine tune-up will be as simple as assessing and replacing worn out spark plugs, while other cars and trucks may require significant adjustments to valves, pumps, engine filtering systems and other components.

While the engine has hundreds of parts that can be examined as needed, standard engine tune-up and maintenance services mainly focus on several engine parts:

• Spark plugs
• Spark plug wires
• Fuel filter
• Fuel injectors
• PVC valve
• Air filter

Spark plugs are always the first components assessed in an engine tune-up because they have a natural shelf life and – even with normal vehicle use and regular maintenance – will eventually wear out. Spark plugs are important because they are responsible for igniting the air/fuel mixture and gets your vehicle moving forward. With old, worn-out spark plugs your engine can fail to ignite fuel properly, which can cause your vehicle to run sluggishly, start poorly, and get reduced gas mileage. If your spark plugs are completely worn-out, your engine may not start at all.
