Vehicles or machinery equipped with full flow spin-on, canister or reusable filters can benefit by including advanced or bypass grade parallel filtration. Incorporating advanced filtration is generally difficult due to impractical lubrication system access, cramped engine bays, and some installation solutions require engine modifications and hardware. An apparatus of the present invention provides advanced filtration when used inside well-known manufactured forms of spin-on, cartridge, or reusable filters. The unit installs as a complete unit, without modifications, or external hardware to any engine at the spin-on filter point of attachment, inside the canister housing, or inside a reusable filter form. The apparatus uses the structures of the normally provided filter to enable a bolt-on installation. The apparatus increases filtration efficiency, capacity, easier maintenance, while providing environmental benefits.
