This project comes from studies and test based on different design realized by Novarossi which have led to the new NOVAROSSI INS-BOX approved by EFRA and IFMAR.
Basically conceived to satisfy EFRA and IFMAR rules to contain the noise within the norms respecting human health without decreasing engines output.
It has contributed to the development of new solution that improves the propulsive output.

After various test on track held by our official drivers, we have produced an accessory that not only doesn't interfere with the normal run of the engine but that, on the contrary, in particular atmospheric conditions, increases the output.
If we look carefully, the underneath, where air filter is fitted, the 4 fins are linked by a ring to prevent the filter from falling out after a collision as it usually happens......

The central part is screwed to the underneath one by 2 self-threading screws so as to avoid loosing the NOVAROSSI INS-BOX after collision; the airing holes have been uniformly distributed on the surface.
Finally the upper side is fixed to the body by a screw which is in the centre and that can be revolved so as to suit the 2 (two) 8 mm holes according to the direction wished.

The screw head has been embedded in order to improve the aerodynamic property and for the same reason we have reduced the size of the NOVAROSSI INS-BOX.

The NOVAROSSI INS-BOX has been tested by foremost drivers on various tracks before sending it for homologation; it is advisable to use our NOVAROSSI INS-BOX not only to improve your engine output and it’s also good for environment.
