When to Replace the Spark Plugs on a Ford Fiesta

Model: Ford Fiesta Fiesta 5, MK 5, MK V - Years 2002-2008
Part: Spark plugs

Maintaining the spark plugs is certainly important to ensure good cold starting and especially excellent engine performance, both in terms of power and fuel consumption; before proceeding with the replacement, allow the engine to cool down; then remove the plastic cover from the engine, pull out the ignition leads, and blow compressed air around the spark plug seats to eliminate any debris that could fall into the cylinders during disassembly; then unscrew the old spark plugs and install the new ones without exceeding the tightening torque, then refit the ignition leads and reassemble the cover.
