PN: 99654207505. - Improved ball bearing pulleys. Reduces motor load by 45%. Porsche genuine is now made in China. Any hardware included with this item may have a different color than whats shown in the item images.
I've recently replaced both regulators, one with the genuine article and one with this URO item. This regulator works smoother and, due to the use of ball bearings as against plain bearings in the Porsche item, expect it to last longer.
