This is an Autococker volumizer. They are made from Aluminium 7075 for lightweight, high strength and the greatest volume addition possible whilst still matching in perfectly with our Inception Pnuematics.
Hidden front allen key hole allows easy install without damaging the outside surfaces.
We recommend the use of this with any Mini Cocker build or MQ valve build to increase the operational tuning window but you can put them on any autococker you like if you feel they would benefit from the extra volume.
