AMSOIL Bypass Oil Filtration Systems and Filters
Choose the direct AMSOIL bypass systems option when you want current systems and mounts, or use the ProEdge guide sections to match a specific Ford, GM, Cummins, universal or heavy-duty route. Open bypass oil filters separately when an installed system already determines the filter family.

Quick answer
Start with the official AMSOIL bypass systems category when you want current systems and mounts, or use these ProEdge guide cards to narrow the option. Bypass filtration works alongside the engine's full-flow oil filter; it routes a controlled partial-flow stream through finer filtration media to add filtration capacity for small particles and soot on supported bypass filter options.
