FX Impact MKI, MKII Expansion Power Plenum has been designed to allow more volume of air behind the valve when the hammer strikes.
This helps increase the power and use slugs in the FX Impact MK1 or MK2.
Most benefited if you have upgraded to slug liners or are using heavier pellets in the factory barrel which shipped with the FX Impact.
The FX Impact Mk1 comes with a smaller plenum and those customers would benefit most from this upgrade.
The FX Impact MK2 has a slightly larger plenum and you would still benefit from this upgrade.
If you have the latest FX Impact MKII with the Power Plenum, we do not recommend you purchase this product as you might not see any further power rise with this mod.
This is a very simple and quick swap for more power.
All you go to do is remove the factory tank and make sure the regulated pressure is zero in the main pressure gauge (near the grip) which shows the tank pressure and the regulated gauge at the rear where the mag loads. Once confirmed both pressure gauges are showing zero, remove the regulated gauge and install the mod.
For FX Impact MKI: Install the mod with the dowty washer.
For FX Impact MKII: Remove the dowty washer and install the mod directly.
Imp Note: The Product has been tested to 400 bar, however, do note the max fill on the FX Impact is 250 bar and you must never exceed the max fill pressure of the airgun at any point in time.
Always refer to the company user manual for the max fill pressure.
