250 Spark Plugs

I just hand tighten them then do 1/4 turn.

Make sure it's clean around the ignition coils before pulling them out or crap can fall down into it.

 

I found they run better when gapping them from the standard 0.9 down to 0.6.

 

25-28Nm

 

Yeah gap to 0.6, and hand tighten mine too

 

how do you gap them down without damaging them. Do you notice a difference

 

Gap tool..... There is meant to be less chance of the engine blowing the spark out

 

I was told to change to a different plug and gap it to 0.6 for remapping, as it helps with the fuel burning with the extra boost.

 

I think you should give Paul a ring at RSTuning and tell him he is stupid and does not know what he is doing....

 

Presumably for a stock 250 the Renault spark plugs are fine out the box and don't need gapping to 0.6? Only for mapped cars?

 

Got a genuine renault service set sat here waiting to fit - with a full set of plugs
Checked them and every one is exactly 0.7 on the feeler gauges

I aint mucking around with them for a 10th of a mm lol

 

It's got the usual RSTuning pre-made map thrown on it
But I've never noticed any problems with the plugs that are in

 

Bumping an old thread here.

I’m getting my Plugs changed on Tuesday and will get them gapped to 0.6mm as most people have suggested this. Only thing is I had my car mapped by RS Tuning about 5 years ago, will it be okay to still do this? Might be a silly question

 

for sure absolutely gap them to 0.6mm, as always be super gentle bending the earth tip as can induce metal fatigue later on

 

what about a R26?...mine runs 270hp..what gap should the plugs be on it?

 

If it’s been remapped and has more fuel flowing into cylinders then makes sense beef up spark with smaller gap

 

What’s the benefit of gapping the plugs to 0.6 mm? Also what are they gapped at from factory?

 

Smaller gap = stronger spark can resist flame been blown out with extra fuel from 630cc injectors
Factory gap is 0.8mm

 

Ah ok makes sense, talking modified engines?

 

what about standard injectors?..should it still be 0.6mm for the mk2?

 

Hi all,

Where's the best place to buy some OEM spark plugs? Renault parts direct?

 

No reason not to, can go to 0.4mm for even stronger but 0.6 is optimal for these engines

 

You all recommend to use oem Renault plugs with gap 0.6?
I have full stage 2

 

I was told to use NGK BKR8EIX and gapped to 0.6mm, had these in 4 different forged engines now not had a problem.

 

Hello guys!
I am planning to install a hybrid turbo st2. Maybe there are plugs that will fit without reducing the gap?

 

You need to reduce the gap to get a stronger spark, higher boost tends to blow out or reduce the spark if they are set as standard.

 

And you also recommend to make it for stage2?

 

Yes for sure, mine was running close to 400hp and were spot on, also had them in before the tuning bits were added

 

but how to make the correct gap
Could you show me tool I needed

 

I don't use them myself, been doing this sort of stuff for decades, but here are some that are available on Ebay

those NGK BKR8EIX are indeed a top quality plug very suited to tuned engines, use a hotter BKR7EIX if just hanging around McDezz car parks

 

Thanks. I ordered already
Tommorow get it and change the gap

 

I ordered today that plugs. I have a question
Is it possible to use them without changing the gap?
I'm afraid it might break off

 

I have gapped 100's and 100's of plugs and have never had one break, as long as your not an animal with it you will be fine
