It is installed, finally: "Not cheap, but a good investment"...noticeably more "umpf" through all ranges... pulls & sounds better = more smiles per gallon

Yes. Although I have to drive a bit more (and probably getting used to the stronger pull and therefor won't be able to tell the difference more precisely), I can already say...pulls better all the way, >3500rpm even better. 
As my 986 is desnorkeled, the air intake sounds even a bit (not obnoxiously) louder now. Guess I have to balance that out with a valve PSE now 

I was skeptical at first, not anymore!
