How to replace Spark Plugs on RenaultSport Megane 250/265/275

Hello fellow CTzens!

Here is my contribution to DIY section:

So, after 60000Km my RenaultSport Megane 250 lost some top speed and when I turn the engine on for the first time every day, it had some kind of “hiccups”. Problem? Spark Plugs!

I bought NGK Laser Iridium not knowing which ones he had inside, but when I was replacing them, I could check that the old ones were the same brand and model.
