340i LCI colder range spark plugs

BMWILUVU · 04-13-2017, 09:39 AM

Can anyone recommend if they have found 1 heat-range colder spark plugs for 340i? I am having trouble finding them for the 340i.

Why would you want colder plugs? These engines run quite hot - 220 or so coolant temps.

OEM seem sufficient enough even if you add boost. Interested if anyone else has input though.

Maybe you are right. N55 plugs look like they are range 7 and ours is 8.
