Classic Mini 48mm Throttle Body Upgrade Stock Replacement Mpi

The stock throttle body on all twin point/MPi Minis is made of plastic. And if this is not bad enough the design only allows it to open to 75% of the standard 48mm bore size. These new replacement bodies are not only cast which eliminates the problems of cracking and throttle sticking in the plastic version but most important they now allow full throttle opening! This unit is a direct replacement with no ECU change needed.
