[FlyRotary] Re: (unshrouded plug ?)required wrench
When
I looked at the NGK spark plug site and looked up my 1989 RX7 13b
engine,
the recommended plug was the one with the extended shank (the part
sticking
out of the engine, above the sealing washer). It does not need the
thinner
"special" plug wrench. I think I'll stick with the NGK BR9EQ
plugs,
and
use my regular old Sears Craftsman deep well socket. Paul
They should work
fine. I just felt that for a system set up for maximum spark power, I didn’t
want to have a big resistance in the plug. I have no idea whether you
would ever notice the difference. I expect Paul Yaw would.
