Mazda 12A & 13B Underdrive Water Pump Pulley spo-disabled washers and spacers as picturedLightweight water pump pulley made from aircraft grade 6061 T6 aluminium for light weight, and black anodised for great looks. Offers faster acceleration through significant reduction of mass having to be accelerated by the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev. Pulley outside diameter is 130mm. Suits early 12A and 13B engines, not S4, S5 or later engines.
