Yes it will. The stock MP3 shifter is the odd ball of the bunch. It has different threading so MP3 can NOT be used with the MSP or Protege shifters and vise versa.
Even though I have a MP3 I bought the TWM shifter for the MSP and bought a MSP stock shift knob. I also have the Kartboy shifter bushings, and reccomend them highly (TWM also makes there own version). With the awsome ball bearing from the TWM shifter and the bushings, there is absolutley no "slop" and the shifts they feel crisp and controlled.
When I was looking for a SS I researched a long time (over a month). After looking at all the shifters I could find (TWM, Kartboy, B&M, ebay knockoffs, etc.) I found that the TWM is the best if you are looking to actually reduce your shift the most and have a good quality product.
EDIT: If I remember correctly you don't need bronzoil bushings for the TWM because of the ball bearing already in the TWM shifter.
