This magnesium investment-cast upgrade is a straightforward bolt-on solution that extends engine life while maintaining the thermal stability your build demands.

  • Patented nautilus impeller design
  • High-flow hydrodynamic geometry
  • Increased coolant flow all RPMs
  • Reduced engine operating temperature
  • Bolt-on installation
  • MPN: WPK-45AM
