Spark plug type ..

Guys

Been to GSF for new plugs today and they say they dont stock WR8AC which I have in at the moment..

They list W7AC for the 1600 tp ..

Got these but not sure of the difference..

Any opinion?

Cheers

The codes-

W= m14 thread
R= suppressed to avoid radio interference.
7,8,9... Heat range. The W7AC is a slightly colder plug. Not far off though, would run fine.
A= 12.7mm depth
C= Copper electrode

So, the only difference is that it'll hold heat a little more, but your radio might be a bit noisier I say try it, you probably have surpressed plug caps anyway and the difference in one grade won't be noticeable.
