The Fleece Performance L5P fuel filter upgrade kit allows you to seamlessly change over from the stock cartridge style filter to a spin-on canister style filter. The canister filter provides for increased filter capacity and longer change intervals as well as expands your filter options.
Our anodized billet aluminum fuel filter base retains the OE sandwich style heating element and includes quick disconnect fittings for an OE quality fit and finish. The new filter base installs in the same location as the stock cartridge filter base.
