you can move it all you want, but sealing it is going to be another issue. it'll probably be easiest to make a mounting plate and weld it on a steel pipe. however, why do you want to do this? you do know there are external MAF sensors that we can use already on the market, right?
if youre doing it because you want to smooth out the throttle body, dont even bother. you won't see any gains from it due to the throttle body not being that big to begin with. you also wont need a bigger throttle body until you are fairly well modified. mod list?
