This is a racing version of Pipercross Air Filter for RSV4
This dual media filter filter offers improved sealing versus the standard filter.
While not proving any performance gains, this filter does have considerable value via improved sealing that prevents debris ingestion.
Filter is also washable and re-usable.
Filter can be cleaned by typical foam (Uni-brand, or K&N brand) cleaning kit.
Filter comes pre-oiled.
Installation note: This filter can be a replacement for AP8104329 "square edges" filter or 858930 "rounded edges" filter because this filter kit does away with the stock air filter brackets
