The new POWER suction silencer is characterized by an improvement in the dynamics of the lower casing, connecting the flow in the direction of the carburettor as much as possible. The new sleeve is designed to minimize the suit of the sleeve, with the carburetor that goes to directly aspirate in the chamber downstream of the filter, of considerable size, approaching the volume limit imposed by regulations, which is particularly appreciated by KZ engines, equipped with carburetor 30 mm venturi.

This very short and inclined 5 ° sleeve is perfectly connected to allow the installation of the intake silencer with an air flow inlet almost parallel to the ground, for maximum dynamic performance. In the package there is a second sleeve with an increased inclination, which rotated in the correct position, allows the installation of the silencer even with angle having a less "dynamic" dynamic, therefore with the entrance slightly pointing downwards, giving more space to the rider if necessary, in addition to being able to adapt also to engines with an inclination of the carburetor very parallel to the ground.

The big news, however, runs the collaboration between KG and SPRINT FILTER, which led to the creation of a new and specific cartridge filter.

Sprint Filter is the world's oldest manufacturer of performance air filters since 1952, as well as current leading supplier of World Motorsport.

KG found in Sprintfilter the ideal partner to greatly improve the quality of the internal cartridge filter.

For which Sprint Filter has developed for KG a cartridge filter (internal) specifically designed for the POWER airbox, using a specific multi-patented polyester mesh air filter with P037 filter media equipped with air passage of 4,500 lit / m² sec. compared to a very high degree of filtration of 37 μm, which allowed it to exceed the strict ISO 5011: 201 filtration standards with brilliance. P037 is also the only air filter in the world to boast of waterproof technology. Sprint Filter, in fact, has the patent that allows it to be the only manufacturer in the world to produce air filters that allow air to pass by repelling water through a special perennial treatment on the filter mesh. Unlike all the performance air filters, the air filter Sprint Filter is really eternal, does not need any oil carrier to retain impurities and regenerates in a few seconds using only compressed air.So this internal filter has a perfectly calibrated polyester mesh, where the interweaving of polyester threads determines a constant constancy of the air passage holes, equal to 37 microns. All filters are the same and do not vary over time. The cotton fabric used in the NITRO model, however, unfortunately has an inconsistency, due to the nature of the cotton, with many "hairpins" that disturb the flow. Involve this interweaving of polyester is perfectly smooth and calibrated. The load prediction is really improved compared to the cotton fabric and above all with great constancy. Not to be confused with TNT (non-woven fabric) in polyester which is in fact a paper with poor performance of air permeability, used in many economic filters.The technological level of this filter Sprintfilter PO37 is of the highest value and consequently the price definitely important compared to the cotton filter of the Nitro model is related to it. Available version with 23mm or 30mm tromboncini, separately also the original support.
