Installed IPD Intake Plenum on 986 Boxster...Pics & Review

[chaudanova]

I believe the modifications for the 986 fitment (compared to stock for the Cayman application) is this larger nipple, and machined back piece.











Here is a comparison of the stock boxster 69mm throttle body next to the upgraded 75mm throttle body. (For simplicity sake, I'll refer to these as 69mm and 75mm, although the actual dimensions measured accurately are more along the lines of 68.xx mm and 74.xx mm). The larger "75mm" throttle body comes on the NA 996 Carreras, 987 Boxster & Cayman, 997TT, 997 NA, etc.





OEM T-pipe removed and new IPD silicone reducers set on the oem intake manifolds.
