I use the Champions. However, spec plugs for the 75 and 76 is the Champion
RN9YC, not the RN12YC. The proper plug is a bit shorter inside the cylinder
than the RN12YC.

My 76 TR6 has just over 16,000 miles and is running okay on the original
factory tune up, however I'm sure that it is not performing as well as it
could. I am going to tune the car and would like some advice on what spark
plugs seem to give the best results. I know that Bosch has the Split Fire
and another with four points but I'm not sure if these are appropriate for
the Triumph. My car is completely stock...any advice?
Thanks,
