DIY : how I did the Spark Plugs Replacement - 2012 Toyota Yaris - 1.5 L Gas Engine

" Yoyo ", our 2012 - Toyota Yaris, arrived @ 160.00 km milestone. At this point, I did a tune-up: changed the engine oil & filter, air filters, brake liquid and now the spark plugs.
Here you can see how I proceed to change the spark plugs.
Doing this operation @home, can save about 100 $ (maybe more) from your pocket ...
Thank you for watching !
Good roads to have, i wish you !
God bless you !
Enjoy !
