FX Power Block (Plenum) Upgrade Kit - Impact X & MKII

The power plenum of the FX Impact significantly enhances its power capabilities, while the rear block functions like a high-performance car's ported and polished intake manifold, effectively handling the transfer of power. This new valve house ensures improved air flow, efficiency, and power potential. The Power Block is particularly well-suited for higher power settings, especially for shooters using heavy slugs, enabling increased velocities and enhanced power output.
