As the diameter of the throttle body is actually 68mm, i must think that the MAF housing and the elbow are the same ... so basically, changing just the throttle body would not give some gain.
Is it possible to find just the MAF housing and the elbow for cheap ?

By the way, does the O'Ring diameter is like these 2 parts : 68mm and should be changed to 74mm too ?


Thanks !
The elbow is OK, it fits the OD of both size throttle bodies as they are the same size outside except that the inside diameter of the 74mm throttle body is 74mm and the inside diameter of the 68mm throttle body is .......68mm. The O-ring is the same for both throttle bodies. The answers are all in that post.
