You what your service manual recommends, not an equivalent. EXAMPE: Polaris installed a V groove in my 2014 verse this recommended spark plug. Fouled up quickly, now a Champion equivalent in a Japanese Z230 2-Stroke had the same problem, but the NGK recommend in the manual works perfectly.
Point is, equivalent does not equal the same. This is a great spark plug "if" you service manual says it's what's installed. (They built the machine they know)
You may get away with an equivalent, but if you know english and engeniering you'll buy the correct plug.
