The BBK replacement conical filter is a direct-fit element for several BBK Power-Plus cold air kits (fits PN 1557, 1712, and others listed). Offered individually to replace damaged or worn originals, the filter restores the intake's airflow and is said to provide substantially better flow than paper elements. BBK recommends using its restore kit with cleaner and re-oil to maintain filtration and extend the filter's usable life.
