Sprint Filter P08 Suzuki Hayabusa (22+)

About Sprint Filter: Established in 1952, Sprint Filter started building high performance air filters and intake systems. Ever since their inception products have always been highly innovative and based on ongoing research and development of new filtering fabrics and intake systems. Sprint Filter air filters are widely gaining in popularity in the world of racing. Many top teams have chosen them, with their better performing polyester filter, for winning the World Championships.

About the P08: Filtration degree of 80 micron, with a guaranteed air flow of 5,000 l/m²/sec. make the P08 a very versatile and efficient air filter, suitable for use on the road but with outstanding performance characteristics. Dyno testing of a 4-cylinder 1,000cc bike without control unit remapping, revealed an extra 2.5 HP halfway through the power curve. They are available for a wide range of motorbikes and scooters.

Polyester - A Winning Technology: On the one hand, air filters have to guarantee good air flow. On the other, they have to filter large particles so they don't end up in the cylinders. The two operations are opposed to each other, and the best air filter is the one that optimizes these two functions. Production motorbikes are normally fitted with paper filters, while the usual solution for sports filters was oil soaked cotton. With its adoption of the polyester membrane filter, Sprint Filter has taken a huge leap forward, making all previous systems obsolete.

Structure: Polyester fabric is extremely permeable and solid and cannot be affected by folding during construction, by the difference in pressure during operationon or by maintenance. On the other hand, the cotton filter has a weft that depends on the overlapping and number of layers used. Moreover, it tends to lose its shape during these phases and, as a result, some zones will benefit from a high filtration value while others will filter poorly.

Main Features:

Steel Mesh: Another step forward has been taken for the P08 and P16 air filters, which once again distance themselves from the competition owing to the use of innovative technologies. After using the polyester filtering element, Sprint Filter is the first company in the world in this market to use steel mesh with epoxy varnish to support the membrane filter. The advantages? The strength of the wire allows a wider mesh to be woven, with the free surface increasing from 66% to 80%, which means the filter can be made with superior structural characteristics.

Using steel instead of a light alloy does not increase the weight. Not only is the mesh wider, but the diameter of the wire used is smaller than that of the past, and this more than compensates for the greater specific weight. Finally, even the look of the filters has now improved: less polyurethane seepage is noticed on the filtering map (orange for P08s, white for P16s and P037s, black for P08F1-85s) so it is better defined.

Air Flow: The polyester air filter guarantees a very high air flow that neither cotton filters (whose permeability depends on the number of layers used), nor OE paper filters can achieve. Remember the simple equation: More Air = More Power!

Filtration: The construction precision of the polyester filter offers a filtration degree equal to that declared and is constant over time. The cotton filter, instead, has extremely variable openings, from just a few microns to several tenths. This means that, initially, the cotton filter has a low filtering power (equal to 50% of a contaminant with a range of between 5 and 200 μ). Only after a dust cake forms on the surface does the filtering power increases up to 80% of the above-mentioned range, but there is a resultant drastic pressure drop. In short, a cotton filter has low filtering power for half of its lifetime, while for its remaining lifetime it has a very high pressure drop.

Efficiency: Many dyno tests have confirmed the importance of a flow with a minimum degree of impedance. A 4-cylinder 1000cc bike (fitted with a P08 filter) without any remapping of the control unit, supplied more torque and 2.5 HP more at half the power curve, in that area that can guarantee a "fuller" response to the throttle.

In its engineering course, Trinity Saint David Swansea University tested the most popular motorcycle air filters on the market, checking the performance of each filter with a Super Flow flow bench. The test was set up in a simple but effective way: different brands of filters were fitted on a square section pipe, through which a set quantity of air was pushed.

The curve distribution is evident: the polyester Sprint Filter filter definitely breaks away from the "group" of cotton filters (among which the Sprint Filter water-resistant polyester filter ranks very well), and sponge filters are positioned at the bottom of the chart. The structure of the filtering elements was then checked under the microscope, and in this case as well the uniformity and compactness of the polyester were obvious.

Maintenance: Maintenance of the air filter is important for the protection, care and efficiency of the engine. A clean and undamaged filter will always ensure the correct quantity of clean air for the airbox.

Fuel Economy: By optimizing the air/fuel mixture the Sprint Filter allows you to consume less fuel all the while gaining more power!
