There are two distinct versions of the 348 coming to light as I find more of these PHS reports. One which clearly states HO(pic below), the other that states RA(as seen above). There's another distinct difference which can't be ignored, that being the price charged for the option 348. There's no denying that there are two different things going on with prices and the ram air designation on the PHS for cars that have been lumped in with HO's in the past. The major arguments against there being two distinctly different designations going on is that there wasn't any way to order differently. Obviously, that is being held 'in error' now with these documents that I have been finding. There must have been two 348's that could be ordered. How else could you explain the big difference in pricing? The difference is consistent. RA 348 with a charge of $350 and HO 348 with a charge of $424. Different pricing means different optioning.... different 348 package.
