I just purchased and installed an EVOMS V-flow intake on my 997S. Very nice product and a seemingly straightforward installation. I have just a couple of questions and was wondering if someone(s) with installation experience could assist. BTW, unless I missed something, it seems odd that while having excellent installation instructions, EVOMS doesn't seem to have any assembly instructions, which is the basis of my questions:
1. The system was freshly boxed with the red-colored filter wrapped in plastic. I'm assuming it comes pre-oiled and so I don't have to deal with oiling for the next 10K miles or so?
2. The filter/venturi(collar)/intake pipe (with MAP sensor) connection was a bit confusing. The collar has three brass threaded holes but there seem to be no screws/holes to fasten it. Is that correct? And in that regard, the collar connects through the hole in the housing into the intake pipe but is not 'fastened' to the pipe other than a press fit. Did I miss something?
3. There is a 90 degree rubber elbow that is part of the parts bag. It seems to be identical to a part already installed in the car that is part of the Helmholtz resonator assembly (from recollection, I don't have the car in front of me at the moment - and, btw, about the funniest name for a car part I've ever heard!). Um, what's it for? Ahem.
Thanks in advance,
