Spark Plug Gap for 74 911
 

Hello - I have a set of NGK BP7ES plugs for my '74 911 2.7. I'm having trouble finding the gap size - I like to check the gap out of the box to be sure they're right - but after looking in the OM and WSM all I get are gaps for Bosch W265s and Beru 265s. So far I have not found a cross reference that helps.

I know the Gap is not a hard & fast rule and can be sized to the engine after experimentation but all i need at the moment is factory SP Gap.

Can someone help?

Thanks!
