Kev this is a mod that my mechanic told me a few months ago and he told me that he could make my airbox like this and now i saw it on otr.Appereantly there are 2 types of stage 3,the one which fixes the problem with the 2 in 1 headers melting the airbox(the off the road mod) which opens the upper plastic and cuts the rest plastic in half and replaces it with a smaller plastic(where the headers pass picture 2),and the other one my mechanic proposed which is like the 2 in 1 with the diffrence you dont cut the half plastic.Next month i will have some experiments with stage 3 airbox and some other mods so i will keep you tuned
