This FX Impact Power Kit 72cc Power Plenum kit contains everything to mount the FX Power Plenum 720, as used standard on the FX Impact M3, to your FX Impact or FX Impact MKII.

With the FX Impact Power Kit 72cc Power Plenum kit, you enlarge the air capacity of the plenum, meaning there’s more air readily available directly in front of the valve, to shoot slugs with more power and velocity.

Of course, you’re still able to reduce the power for lower velocities. Added advantage of the larger plenum is the fact that regulator pressure can now be set even lower for extra accuracy.
