Out of Stock. Available for Pre-Order.

*This kit is for M3 (non-power block) Impacts.
As much as the power plenum stages the power capabilities of the Impact, the rear block handles that transfer of power much like a hot-rodded car’s ported and polished intake manifold. This new valve house allows better air flow, efficiency, and power potential. The Power Block works best for higher power, especially those shooting heavy slugs, allowing higher speeds and power. 
*This kit is for M3 Impacts. If you have a previous version Impact (MKII, X, etc) you will want to the purchase the kit that includes valve rod, air tube end, air tube, valve hous & power block here:
