Daily driver in the Washington, DC area (except when the snow is higher than the fenders). No Auxiliary Air Valve (also known as Secondary Air Gate or Auxiliary Air Regulator), no vacuum limiter, no air diverter valve, no switch over valve, no check valve x 2. OK, those last four are all part of the Secondary Air Injection system and I have it now in my secondary parts bin.

Results - runs better, starts require a 1/4" press of the accelerator when it is cold (just like it used to be on all cars) to offset the spray from the cold start valve. I think it is a bit quieter, too.
