someone in my other post brought up that he had measured his stock throttle body and it was 66 mm. so I just checked to see the size of my stock throttle body. The butterfly is approximately 58 mm. The inner edge of the outer housing (inside diameter) is closer to 66mm . I would like to go to the BBK 66 mm if that is the size of the butterfly. My question is the butterfly the proper place to measure? anyone measure the stock against the BBK? is it really bigger?
Sorry for all the questions but I thought it was better to ask before I order it!
 






I did and its just slightly bigger, I notice a nice diff after installing it...
 






thanks I will see about getting one then
