How to replace spark plugs in Qashqai

The replacement of plugs in Nissan Qashqai 1.6 L requires some efforts since the access to them is complicated. Remove protective cover from engine, unscrew air duct and throttle plate (unscrew 4 bolts with wrench 8), then remove discharge manifold (unscrew 5 bottom bolts and 2 side bolts, for this purpose you will need wrench 10). Then unscrew ignition coil (wrench 10). Only after that, you can replace spark plugs.
