Hello All,

We have a spark plug removal procedure, and a written tutorial of the process below, enjoy!



Remove the top engine cover by pressing these 4 buttons.



Remove the 2 - 10mm bolts holding the side covers on under plastic caps which can be removed with a screwdriver.



Remove the 10mm bolts holding the coils, then use a flat head to unclip the wiring harness. Inspect rubber boot for any signs of damage.




Use a spark plug socket with a rubber grommet to grab onto the spark plug assisting with the removal process.




Put little anti-seize on your spark plug threads and carefully lower and tighten your spark plug to 18 ft-lbs. 




Reinstall your coils and tighten back in reverse order. Great job!
