And these are definitely the ones I need ? I’ve found these for ?10 ish each. 👍NGK ILKAR7J7G (91121) are the plugs you want.
Usually around £15 per plug.
Ok, I’ve just removed the plugs and they are Denso. Condition looks ok and they’re a nice colour.
What should the gap be ?
No idea, they don't list the gap.
Somewhere between 0.7-1.0mm should be fine.
I’ve set them all to .8 mm, should be in the ball park then.
Nearer .9mm
The genuine Renault plugs were denso I'm sure! Thymey definitely weren't NGK! I remember doing a first service on one and being surprised when I pulled out non NGK plugs
