I wonder, though (and this is purely theoretical hindsight) if the decreased performance caused by the NOX setup actually caused more emissions? I have been installing electrical fans on most of my older cars, and removing the water pump fan. They warm up faster, and are more efficient since the fan only runs at idle. Prolongs the life of the water pump, too. I wonder why they didn't do that instead? > had to reach an overheat condition before the vacuum > advance would start > working.
