there appears to be left/right fence on the main tube and what I am suspecting as a split butterfly plate that adjusts the angle with air speed?? pic attached
if so, Techno Torque features are quite in-line with latest boxster engine intake design!

Thanks for pointing that out.
That's one of the reasons why I couldn't get any better performance from the 987s.
Those cars were tweaked by the factory to get the most and just about any change you make will result in a net loss of either HP or Torque or both.
Happy Boxstering,
