Mazda 12A / Early 13B waterpump with billet impeller

-Brand new waterpump fitted with billet impeller upgrade.
-Impeller machined from aircraft grade 6061 T6 aluminium.
-Black anodised for longevity.
-New gasket included.
-Fitting instructions included.

Fits all 12A and 13B engines from RX2 thru to Series 3 Rx7. (Will not fit twin distributor engines).

This impeller is designed to eliminate cavitation, increasing waterpump cooling efficiency and flow rate, and freeing up a little extra HP at higher rpm. Not only is the blade design vastly improved over factory, but impeller to housing tolerances have been reduced to aid with proper waterpump function.

A must for high rpm engines, and any application that has excessive coolant temps.
