POLINI Evolution adjustable intake pipe 26 to 28mm carburetor (Ø31mm fixing) minarelli horizontal (nitro, aerox)

Here is the very last adjustable POLINI EVOLUTION intake pipe! This pipe is really at the top, first of all you orient it as you wish to place the carburetor as you want! Its position is designed for very large carburetors and its internal diameter too (31mm, for 26 to 28mm carburetor).



Its fixing diameter is Ø30mm. To avoid harmful vibrations and jolts, the sleeve is made of specific Viton. Rigid enough so that the pipe does not crack or break when tightening. Even on the aesthetic side, we feel that POLINI has really taken care of this piece as desired. No need to put a seal, a seal is pre-integrated into the junction, moreover it is delivered with instructions, screws ... Clearly, thanks to a perfect diffusion, a absorption of vibrations, a good position ... The performance gain will be present!
