yes but the ma12 rad is bigger as it holds more coolant and peitro is running slightly more power than ur ss so a ma12 rad will help a little,
a ma12 rad holds nearly half a litre more coolant than a ma10 rad so the ma12 rad is better.
marks k10 ss did this running hot temps stuff and i suspected it was down to it running lean so peitro get it setup on a rr
