In fact 2-3 sets changed whenever, will be found infinitely better than one crazy priced set never refreshed over the same period, if indeed, which I doubt, they'll last as long anyway?

i couldn't be arsed to change up from 0.6mm either. Just set it narrower, I don't think it truly all that critical after that. Especially if like me, you run a 'past its best', high-miler.

You want to avoid Silver plugs and Platinum plugs. Iridium plugs are ok but no real need for them. You also want to avoid any plugs with more than one prong.

Brisk Silver LPG plugs - as yet I have not seen a set that any engine could even run on. I have also seen the plugs fall apart. The marketing behind them sounds great but they just dont work

Just thumbing thru' in my 1999 V70 owner manual and for my engine anyways, they quote the gap as 0.5mm.

So there.

Jeez.

One thing is clear, I'll not claim 'pro' status, but if 'Classicswede' has seen problems with snake-oil LPG/CNG plugs then that bears out my own more limited experience. Thank you 'Classic'.
