Spark Plug Replacement (Set of 4)
Spark plugs are responsible for igniting the air-fuel mixture in the engine. Worn-out plugs (with carbon buildup or incorrect gaps) cause misfires, which strain the ignition coils and can lead to expensive catalytic converter failure.
Signs that replacement is needed:
-
Rough idling or engine shaking, especially during cold starts.
-
Poor acceleration and lack of engine response.
-
Increased fuel consumption.
-
Difficulty starting the engine.
What is included in the service:
-
Removal of the engine cover and ignition coils (or spark plug wires).
-
Cleaning the spark plug wells with compressed air (to prevent debris from falling into the cylinders).
-
Removing the old spark plugs and inspecting them (diagnosing engine health based on plug color).
-
Installing new spark plugs and tightening them using a torque wrench (strictly to manufacturer specs to avoid damaging the cylinder head threads).
-
Inspecting the ignition coil boots for cracks or wear.
