250 Let's talk coil packs

My car is pushing 200k km so I've been getting a bit of smoke, some misfires at high speed and some times it takes a bit longer for the engine to start. After changing the spark plugs, thought of treating the car with a nice set of ignition coils, to see if that fixes anything.

The question is should I go for the OEM ones or is something better out there?

 

0.6 and oem plugs but my question is about coil packs

 

Nope! my question is about the coil pack. Let's take things one at a time. The misfire for now is my problem and maybe I will make a seperate topic for it. I've just gave you bit of context with regards to why I am looking for the best coil pack.
...

It seems OEM Renault it is. Thank you.

 

Pump, injectors and filters are new. But this gets steered in the wrong direction. I guess stock coils do fine.

 

I don't remember exactly but I think it was 350 euros OEM new

 

So, I've changed the coils with OEM ones. Wow!? quite a price on those! Almost 80e vs. 30e for aftermarket ones.
...
So I went to the mechanic and one of my old coils you could literally remove by hand. Thing is that I've changed spark plugs a lot in my 200k and it payed a token on the thread from the screws for the coils.
...
For those intrigued by the misfire, it was the turbo MAP sensor. On the 250 it is not fixed with a screw and it can pop out in time. See the attached photo.

So after changing coils and fixing the MAP sensor my car pulls like a train.

I didn't change it, just fixed it in place.

 

Recently I've been experiencing some more missifire on heavy load. After discussing with the tunner I've used 100 octane gasoline and the problem is gone completly, 100%. It seems the problem was the quality of gasoline. Since I'm not dutch and my car is an import, the quality of petrol or gas or whaterver you wnt to call it is a lot poorer than my home country. Maybe it is the ethanol mix they use to boost octane figures... anyway, now, till I get to see the tunner again, I have to stash on octane boosters or drive to Germany regular for that sweet 102.
