What are the correct spark plugs to use on the E31 B12 5,7 ?

Alpina recommends BOSCH F7 LCR, which nowadays is replaced by BOSCH FR 7 LC 2

BOSCH ZÜNDKERZE FR7LC2

Elektrodenabstand [mm]: 0,7

Schlüsselweite: 16
Anzugsdrehmoment [Nm]: 28
Pol-Anzahl: 1
Gewindelänge [mm]: 19
Gewindesteigung [mm]: 1,25

so ... should be 0.7mm

excellent !

thank you !

I can not locate these spark plugs here in the USA. Is there a place in Germany ?


thank you again

Did you check on ebay - if there are some sellers shipping to the US ?

I tried to research an replacement for this ... but it seems that even this cross-refernce-guide is not 100% correct. So - use with caution.
