The valves POLINI are of good models, the slats are models 0,30mm in carbon high quality in order to exploit a range of power higher than the origin, less clamping the high revs ... The base is in rigid ABS, we will appreciate the stop fasteners by vix / nut, unlike the valve box without nuts or the screws will quickly turn in the vacuum ...
The box is well studied, it is in addition now delivered with a studied diffuser (called venturi by some). Stop slats are drilled and studied! Ultimately, this valve box is a very good model that can be used for the best with a carburetion of Ø17, 5mm to 24mm, and an intake pipe aligned with the diffuser. A preparation of the diffuser is strongly recommended if you pass a carburetor of more than 24mm! It is better to prepare and preserve the broadcaster than to delete it!
