40th Steve - Reference Streather, the difference between the 3.6/M96.05 and 3.8/M97.01 boxes, other than the plate, was the 3.8 box had a vacuum resonance flap installed. Air flow-wise, I’m not sure. Both 997 boxes are more air tight (keeps intake air cooler) than the older M96 box and visually look to have more interior volume.

95% certain it will fit. Only change for 3.8 is a vacuum flapper valve not used by 996 engines anyway. I don’t know of any empirical data to support improvements for one over the other. I also like having the correct displacement displayed.
