Experienced tuning experts at the R&S STAGE6 workshop have developed a new suction system that allows you to get the most out of your MINARELLI AM6 or DERBI engine : high flow STAGE6 R/T High Flow 28mm DERBI /AM6 suction manifold (for PWK carburetors 19 - 28mm) The High Flow intake manifold is made of high quality aluminum, the impeccable finish was achieved using the most advanced CNC technology. The suction manifold is anodized black and comes with the well-known STAGE6 laser engraved logo. The High Flow intake manifold is ideal for tug-of-life and racing, it is slightly wedge-shaped to allow the use of a larger carburetor. Thanks to the inclined angle, the carburetor can be adjusted again on the left side of the vehicle and aligned to make room for greater suction with a larger racing air filter. This is not the only special feature of this intake manifold, it comes with a 32mm adapter ring, the intake stroke will be perfectly adapted to the filling in the lamella valve. In terms of performance, the High Flow intake manifold has some key advantages: gas flow has improved and the option of better positioning of the unirded air filter improves the air intake. This results in stable, improved acceleration and better production in general. For even greater performance, we recommend combining the inclined suction STAGE6 with a 10 mm spacer placed under the lamellar valve. attention! The intake manifold is delivered without a rubber adapter for the carburetor, you can choose the right adapter based on the type and size of the carburetor: - 21mm per Vegetable Garden carburetor - 30mm for PWK carburetor from 19 to 28mm - 32mm per carburetor 30mm AND above PWK Included: High Flow Intake Manifold 28mm 4x BTR M6 x 20mm screws BTR M6 x 12mm 6x washers M6
