Hey,
According to forum posts, manual states plugs should be gaped to 0.9mm. As I had my car converted to lpg, I decided to visit specifics shop, which sold me 0.8mm spark plugs, suggesting that I should get them gaped to 0.7mm. Is that correct, or will 0.8 do?

I have BOSCH N08 FR8DC (no idea what that means, are they platinum, iridium?...)

 

This is the updated TSB guidance for all X300 AJ16 engines, normally aspirated and supercharged:

EBC 8143 = Champion RC12YCC(if one can find them) or RC12YC
0.9 mm (0.035 in)
22-28 Nm (17-20 lb ft)

Thanks for the reply,
But you see, LPG converted vehicles need different spark plugs, usually it's all in the gap. So I'm wondering if .8mm will do do, or I'll need .7mm...

 

You post #1 stated you converted to mpg, not lpg. I'm sure some one with information will be along soon.

 

Thanks for pointing that out, didn't notice it lol

 

Ah gotcha, I did wonder about the "mpg", now that makes more sense

Good luck, I have no idea about LPG.
