Fits Series 4 Rx7 waterpump housings (2 bolt thermostat housing).

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.
