Champion Spark Plugs

[tr6taylor@webtv.net (Sally or Dick Taylor)]

John---The N9.....plugs never lasted too long (5,000 miles +/ )in my
'73 before startig to misfire. The hotter N12's would run for twice
that, so this is what I used. After installing the MSD, I can run a much
colder plug, like the N7, or its Bosch equivalent, WR7DC, and they last
"forever".

For more info on plugs, see the attached. Triumph 6 uses the 14mm with
the .750 reach.
