This filter allows for massive airflow but can let a great amount of particulates into your engine during normal street use. Great in a track bike, asking for long term issues on daily drivers.

Put this in my race bike. Along with a Holeshot Performance exhaust and PowerCommander, I saw a beautiful jump in HP and much more smooth. Haven't done anything to the filter other than cleaning it since I bought it in 2007. Still works great.
RACE filter: The difference between standard and race lies in the “filtering package”, making the air passage to engine concept even more extreme: the RACE filter has an even greater air breathing capacity compared to the standard one and its installation is only, exclusively advised for motorbikes used on a race track as carburetion or injection could be weak (for carburetion the air quantity present in the mixture is greater than the quantity considered necessary, while for injection, despite the modern gearcase capacity to adapt itself within certain ranges, at times the excessive air increase is not handled correctly by the gearcase itself).To avoid problems of this kind and recover the right stoichiometric air/petrol relations, you need to increase petrol capacity. To do this, you normally use a gearcase, remapped or replacing the original. Otherwise for carburetion motor bikes you can have additional carburetion kits.
RACE filters have the words “RACE” on their recognition code (e.g. FM 482/08 RACE) and a yellow line inside the filtering package making them easily recognisable.
