yeah they are not EXACTLY the same...But so close that i used the M54b30 intake boot on the M52Tu25 intake manifold...beside each other they are very close in size... it is only the MAF section which is larger but not the actual throttle body.. i would suspect that this would allow for greater air flow but not by a marginal amount...
