FX Impact Power Plenum Upgrade Set



This original FX Impact power plenum upgrade set will bring your FX Impact to a whole new level as at opens up the ability to shoot an even wider variety of airgun projectiles (Slugs) at optimal velocities.
The Power Plenum adds an extra amount of regulated air what will result in a better efficency of the rifle with higher power levels and a lower regulator setpoint.

FX Impact Power Plenum Benefits:


1. Higher velocities can be obtained. For instance, the standard .22 caliber FX Impact previously achieved 32 Ft/Lbss. of muzzle energy with standard pellets. With the FX Power Plenum added to the .22 caliber Impact, though tuned from the factory to still shoot at 32 Ft/Lbs, you can now adjust the gun and shoot heavier slugs and obtain as high as 60 Ft/Lbs of Muzzle Energy.

2. Lower velocities still available. While the higher powers are now achievable, often shooters want lower power to for different shooting situations (or to simply extend shot count). Thanks to the internal part changes to the Impact, the lower velocities can still be achieved.

3. Increased shot count per fill. With the FX Power Plenum, the 75 shots per fill that the standard tuned .25 caliber Impact previously achieved, is now increased to 110 shots per fill. That’s just one example.

4. Lower regulator pressure required. You get the same velocity result with lower regulator pressure due to the FX Power Plenum. Lower pressure will also result in less wear and tear maintenance to your rifle, says FX Airguns.

Installed on all my Impacts, wouldn't be without it, combine it with the Huma Regulator and the gun is something else.... installation is simple if you follow the online videos... yes, it is a full strip down but only nuts and bolts... no special tools required.... highly recommended.

Super fast shipping to United States. Faster than most in state places. Great product, and easy to install. All the orings came already setup on mine, so no worrying about which one went were. I put this on my impact Gen 1, and works great.

Super fast shipping to United States. It’s faster than most places here in the states. I have a generation one impact, and it worked flawlessly. All the orings were already installed when I got it, so all I had to do was watch the video on how to put it together. Works great

I added the transfer port kit along with the Power Plenum kit to my 30 cal Impact X and took it from a 78FPE rifle to a 98FPE rifle without touching any regulator pressures or tuning. Huma shipped both kits super fast to USA. As always a great shop to do business with!!
