Y-Type Oil Return Manifold

The Y-Type Oil Return Manifold by PETERSON FLUID (MPN 10-1725) is an essential component for any serious engine builder or performance mechanic working with external oil cooler systems, dry-sump setups, or custom supercharger/turbocharger installations. This manifold consolidates multiple oil return lines into a single, efficient pathway back to the engine sump, eliminating the need for cumbersome hose routing and reducing backpressure in your cooling circuit.

The Y-Type configuration merges multiple inlet ports into one outlet, allowing oil from separate auxiliary circuits—such as turbo coolers, transmission coolers, or supercharger oil supply loops—to combine into a single return line without turbulent mixing or pressure spikes. This precision-engineered manifold is designed to ensure clean, organized plumbing that maximizes flow efficiency while protecting engine longevity.

The compact 4.85 x 1.7 x 6-inch design minimizes underhood real estate while the lightweight construction keeps parasitic weight to a minimum, critical for performance builds where every pound counts. Threaded ports are precision-machined to accept standard automotive fittings, accommodating both -10 AN and -12 AN line sizes depending on your cooling system arrangement.
