Hi, I came across this thread this morning while looking for a solution to my own induction problems.

A solution being put here is to use the 997 plenum. Now this does not curve unlike cayman/boxster plenums.

I currently use the engine & induction setup from a late 3.6 996. Now the plenum angle is similar to that of the 997. The issue it gives is that to connect the TB to the airbox you have to immediately use a v sharp immediate 90 degree bend in order to clear the bulkhead to the rear of the luggage compartment.

My feeling is that any gains from this plenum will be negated by this v tight 90degree turn into the TB. I can provide pics if that helps.

Any thoughts??
