Hi,
Which is the best spark plug for E30 applications?
I heard NGK 97506, as well as BMW 12120042724 FLEX FUEL SPARK PLUGS.
Which gap to use?
I'm currently on a Bootmod3 stage2+ e30 tune. Might go Pure Stage 2 in the future. Won't be going full E85, just keeping E30 for fuel economy.
Thanks in advance.
