The word on the "street" has always been that the black injectors flowed more fuel, but I couldn't tell the difference, even when I took one of each apart. The orifice parts are REALLY small, however, and I don't think I could see or measure a difference that would make a 1 part in 15 change. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
