Hey guys,
i just noticed in the TIS that the recommended plugs for s50b32 is NGK pkr7a, but on the lower line it says
NGK BKR 6 EQUP (High Power) ECE as of 9/98
I'm wondering what that's about. Being a 6 number plug it runs hotter than the pkr7a

the thread sizes dont match 12mm vs 14mm
Does anyone know a 1 step hotter replacement plug for the s50b32?

IIRC, the NGK DCPR*EIX plugs will fit. You have a larger heat range there, and they are way cheaper than the weird PKR7A.
