Fleece Performance L5P Fuel Filter Upgrade Kit 2017-2022 Silverado/Sierra 2500/3500


The 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.
