Anyone successfully install an Injen PF1959P Powerflow CAI in their 05+ Xterra? They only list this for the Frontier and Pathfinder, anyone know why? Differences? mounting? transmission lines? I contacted the mfg. and the reply I got was that they had never actually installed one in a Frontier so they could not comment. I know that the only difference on the Volant for example is the addition of a scoop on the model for the Frontier version other wise they are exactly the same (verified by Volant). I cannot see there being any difference in geometry or fitment from the Frontier to the X for any CAI..., am I wrong?
