Air Venturi Avenge X - 16cc Power Plenum. Please Read!! Volume measured with liquid.

Please message me if you need one of these, and it's listed for $500. Please don't purchase if you see this listed for $500. You will be charged $500!

Price is actually $120 plus shipping as these are a two piece item. A non degassing plug will also be supplied. When this is out of stock, the price will be set to $500 to keep the listing visible / searchable. I am able to make these in the handling time my listing state. Should you want one, please purchase at the process shown and it will be shipped. 

This plenum is measured to be 16cc in size at it's current length and extends about 3" inches from the base of the receiver (approx. 2-1/4" showing when in the stock) and is 1" (25.5mm) in diameter. The small thread is M10 x 1.25mm, the same as the  blanked off thread in your receiver.

This will increase the plenum size from the factory 15cc to 31cc Many of my customers were happy with their tune but wanted more shots per fill. Plenums are great for that, too, with reported regulator pressures of 300 psi less and still achieving the same 'pre-plemum" power / fps figures.

This plenum is made from USA made 7075 T651 grade aluminum bar, by a (now) American, in rural Pittsburgh PA. I'm not a big business, just one guy trying to grow a fledgling business.

The plenum screws into where the access screw is, next to the regulator. The regulator restrictor screw needs to be removed, and the bonded seal from the access screw needs to be reused on the plenum. Add a little pure silicone grease to the oring before fitting.
