K&N 16" XStream® Air Flow Top 66-1601.
K&N XStream Air Flow Tops are innovative round filters designed to replace a metal air filter top. These filter lids add more filter area and are designed to increase horsepower and dirt capacity. Washable and reusable, the XStream Air Flow Top filter delivers outstanding protection for your engine.
K&N part number 66-1601 has a unique 16” diameter; which was designed to be used as a replacement lid for one of K&N’s low profile 16”, or equivalent, air cleaner assemblies.
K&N XStream Air Flow Tops are also available in 9", 11", and 14" diameter replacement tops as well as full air cleaner assemblies.
For increased protection and style, K&N offers Precharger® filter wraps in a 16” diameter that can be used in conjunction with one of these low profile Holly Dominator air cleaner assemblies. Prechargers are made from a durable polyester material containing uniform micron openings which will stop small dirt particles; yet add little restriction to the airflow of the filter. A K&N Precharger is recommended for extra protection in off-road or dirt track racing applications.
