Since Sprint Filter began to produce air filters, in 1952, the way to build the filters changed, most  of the competitors have remained stopped to the pits  manufacturing the classic cotton gauze oiled filter, Sprint Filter ,not considering it in the step with the times, studied a NEW REVOLUTIONARY SYSTEM: THE FILTER polyester P08, a filtering membrane made ​​of a woven synthetic yarns.

From the technical point of view, the filter element Sprint Filter P08 is not made, as generally happens, from stranded cotton fibers  or more simply by oiled foam, with a calibrated or variable density, but by a filtering membrane consists from a fabric of polyester threads from ø 5 microns, that you can simply  clean  with compressed air!

Moreover, the filtering surface area appears to be double (compared to all the other special filters) : the use of this special polyester allows to use  a fold step (distance between a pleat and the other one) of 8mm against a standard of 10/12 mm of all other special filters on the market; Sprint Filter, moreover, is the only one who uses a height of the pleat of 20 mm. Against a standard of 15 mm. This results in a greater filtering surface area and a constant filtration at all the engine rounds. The airflow ensured by the filters P08 is not comparable to any cotton air filter and it is constant over time.
Finally the cleaning procedure, is extremely fast and easy: just use compressed air in the opposite direction respect to the inlet intake to remove most of the retained dusts. You do not need  to wash and dry the filter anymore, allowing an immediate refitting. If  a grease elimination is necessary, seeping oil , P08 does not fear any degreasing agent, of any kind it can be.Than after the washing with degreasing agents it can be safely blown with compressed air and refitted in the airbox.

The three images below show from left to right: a BMC filter, a K&N  filter and a Sprint Filter
After watching them are you always sure you want a medical cotton gauze inside your bike air box? Or do you want an innovative product? This is the question that we of Carpi Moto made ourselves as soon as we compared the three products and it’s the reason why we chose to sell Sprint Filter.



  • ROAD - STOCK BIKE : P08 Sprint Filter air filters are designed to be used on original motorcycles.
    Replace the original paper filter without modifying the ECU mapping . The airflow, while being greater than the original, does not affect the correct working of the motorcycle.
    The first advantage for a stock bike is SAVING MONEY:
    • Replace Air Filter once in the motorcycle life.
    • Fuel Saving at same engine performances.
    The second advantage for a stock bike are the PERFORMACES : There are cases in which replacing the original air filter with a P08 also brings advantages in terms of performances. To support this theory Sprint Filter turned to the Test Centre of the oldest Italian motorcycle magazine : Motociclismo. In this certificated center a true stock Honda CBR 1000 RR air filter was replaced. The result was remarkable: 2.5 hp  gain !


  • RACE - STOCK AND RACE MOTORCYCLES: P08 Sprint Filter air filters are designed FOR RACE USE.
    Maybe not everyone knows that Sprint Filter has developed this type of filters starting from the SBK in 2009  with the Honda Ten Kate and Honda Althea and then step by step with all the top Teams, winning for example the world championship in 2011  with Team Ducati Althea ,  with the DUCATI 1198 rided by Checa.
    After tens of tests made everyday by teams from all around the world on the dynamometer benches, flushing benches and comparative tests on the track, with pressure sensors inside the air box, Sprint Filter can  report that, compared with the best 2 layers RACING air cotton filter, the air filter Sprint Filter P08 is able to lean the air fuel mixture from a minimum of 1% up to a maximum of 5% (depending on the architecture of the engine), but mostly it is evident that the load losses in the airbox are much lower than the cotton filters (2 and 4 layers) and the sponge for sure. The results become more evident and laden with the maximum speed of the air inlet in the airbox. The membrane structure of the P08 makes it possible to pass a precise amount of air through the calibrated holes and lower pressure drop is even more pronounced than any other special filter at speed motor rising.
