Great tutorial, I managed to replace my spark plugs very easily thanks to the explanations. It's very clear, no more details needed. Thanks to the author!

For my part, this tutorial is very well done and gave me the necessary information to carry out this operation on my vehicle. Very sufficient to estimate the time required and the associated constraints.

Thanks to the author.

This tutorial seriously lacks detail (precise references: diameter, length, etc.) regarding the tools to use to change the spark plugs. As it stands, this tutorial is not usable. It absolutely must be completed.

I made a similar tutorial on clio 2 1.2 16v. To change the spark plugs, you need a thin 12-sided socket in 14, tightening to the torque preferably (23N.m).
