To access all the spark plugs, I had to remove the air filter box and a part of the intake manifold, which was a bit tedious. Afterward, I just had to disconnect the plug and could unscrew the spark plug using a spark plug socket. I applied a bit of ceramic paste to each new spark plug and then reinstalled them with a torque wrench (in my case, 25Nm - check the manual if unsure)....

Remove the cover plates to access the frontal lights. Ensure to reconnect the bulb in the same orientation. Pay close attention to the polarity; the little rectangle should face downwards for the inner lights and upwards for the outer lights. Reversing the polarity may cause malfunction or damage. Always double-check the orientation to avoid potential issues with reverse polarity.
