hey guys,

does anybody know whats the difference between the sirio on-road plugs and
sirio buggy plugs? I ask because i ordered some of them for my xxxv and it appears they are
turbo buggy plugs (body is black). I have s6 and s7. Can i safely run with them in my sirio?
And if so, which is the most common number you run on your xxxv, s6 or s7? I run with 16% nitro
and stock head shims.
