Replacing Engine Spark Plugs

Model: Honda Accord MK 7 - Years 2002-2007
Part: Spark plugs

Gently remove the plastic cover protecting the engine by unscrewing the four retaining screws. To avoid mixing up the cables, disconnect only the first spark plug. Using a 10mm socket, unscrew the retaining nut of the first spark plug and pull the boot upwards. At the bottom of the well is the first spark plug. Before proceeding with the removal, thoroughly clean the wells with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the appropriate spark plug socket, which has a rubber gripping device, gently insert it onto the spark plug head and unscrew it. Be careful not to drop foreign objects into the well. Replace the spark plug with one of the same model, carefully inserting it into the well, always using the appropriate socket and turning it gently to ensure it screws in correctly. If you encounter resistance, remove it and try again. Spark plugs should be tightened with a torque wrench; if you do not have one, screw them in without over-tightening. Proceed with the same operation for the other spark plugs.
