Product Details
K&N 66 Series XStream Custom Air Cleaner Assemblies
Upgrade your classic car, hot rod or performance build with a K&N 66 Series XStream Custom Air Cleaner Assembly. Designed for compatible carburettor and throttle-body injection applications, XStream assemblies provide filtration from both the filter sides and the top plate.
Unlike a conventional solid air cleaner lid, the XStream top plate uses pleated filter media to create additional airflow area. This dual-entry design allows air to enter through the perimeter filter element and through the top, supporting high-flow intake performance in a compact open-element assembly.
Each assembly uses K&N layered cotton gauze filter media supported by epoxy-coated aluminium wire mesh. The durable construction is designed to maintain its shape during operation while helping capture airborne contaminants before they enter the engine.
Available in selected finishes, including black and polished-style options, K&N 66 Series assemblies can complement a range of engine-bay styles. A secure sealing design helps reduce the risk of unfiltered air bypassing the filter element.
K&N XStream filters are washable and reusable, providing a serviceable alternative to disposable filter elements. With suitable cleaning and re-oiling products, they can be maintained as part of your regular vehicle servicing routine.
For additional intake surface area, classic open-element styling and reusable filtration, K&N 66 Series XStream Custom Air Cleaner Assemblies are a practical choice for performance-focused builds.
