Yep, optional. *Most* have the standard black hoses, typically you'd find the silicone hoses on cars used in harsher climates. It really all depends on how the department ordered them. Some just check every option (ie We've seen CVPIs that were used out in the desert and have a block heater lol)
Obviously the one near you used to order their's with the silicone hoses and 'aircraft' clamps but no longer does. The option still exists, though. Many departments ditch the cars before they would benefit from the silicone hoses' extended service life anyway.
well look at that learn something new everyday. i allways heard that the pcm was "tweeked" but it was just hear-say, so i guess that interceptor pcm i got around here somewhere is useless? damn
i do like the new alternators with a one way clutch in the pulley.
