Here is the POLINI Evolution adjustable intake pipe for mécaboite engine DERBI euro 1, 2 & 3! This pipe is really on top, first of all you direct it as you wish to place the carburettor as you want! Its position is provided for very large carburettors and its internal diameter also (40mm, for carburettor from 30 to 34mm).

Its fixing diameter is from Ø38 to 42mm. To avoid harmful vibrations and jolts, the sleeve is made of specific viton. Stiff enough that the pipe won't 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 at the junction, moreover it is delivered with instructions, screws... Clearly, thanks to a perfect diffusion, an absorption of vibrations, a good position... The gain in performance will be present!
