dont have the box it came wit, so markings like #'s or letters is what im looking for. have a set of b16 cams and they look pretty identical to the itr ones. they have diff. letters like a G for the b16 cam (not sure if int/ex) and a H for the itr cam. i know they are diff letters but im thinkin the reason behind that is because the b16 cams are from a jdm motor and these itr cams are from a usdm/cdn model type-r. thanks fellas
