  Q: What is the importance of spark plugs in engine efficiency and how should they be maintained on Nissan Juke?

  A: The spark plugs work in harmony with the engine to produce high efficiency and it is good practice to fit the correct spark plugs for the vehicle. If the correct type is used and the condition of the engine is ok, then one rarely needs to look at the spark plugs before their scheduled time for renewal. Cleaning is almost never required and if it is, it has to be done with specific tools so as not to harm the fabric. In special, for 1.2 litres of engines the air inlet hose needs to be removed and in case of 1.6 litres the inlet manifold has to be taken off. Remove the terminal connectors from the four ignition coils and use a wrench to remove the retaining bolts and to pull out the coils from the spark plugs. I would recommend that the spark plug recesses should be free from dirt and hence should be cleaned before the cylinders are filled with the dirt to clog them. Remove the plugs with a proper tool to ensure that they are properly placed on the side so as not to break the ceramic insulator. The appearance of the spark plugs can also give an indication of the condition of the engine; cleaned, white insulator indicate either a hot spark plug or a problem with the management system, hard black deposits may show a problem in the system. Black and oily in nature, if the plugs resemble this then there is more than likely wear to the engine, light tan to greyish-brown would indicate a healthy engine. The spark plug's electrode gap is essential to efficiency, and it should set accordingly to its standardized measurement. Tighten to correct position the outer electrode with feeler blade while the centre electrode is not to be bent or curved for avoiding the crack at insulator. These include motor accessory shops from which special tools for adjusting the gap are available. Ensure that the threaded connector sleeves are screwed tightly and that the areas of contact of the plug require assembly are clean. Each of the plug is to be inserted by hand and when done the right side of the thread is to be brought inside till an equal torque is reached with the torque wrench. Replace the ignition coils, and tighten the wiring connectors; replace the air inlet hose on the 1.2 litre car or the inlet manifold on the 1.6 litre car.
