-16 Inline Scavange Filter

The Peterson Fluid -16 Inline Scavenge Filter (part number 09-0405) is a precision-engineered oil filter designed for high-performance engine systems requiring dedicated scavenge line filtration. This aluminum inline filter uses straight-through design with -16 AN male ports on both inlet and outlet, enabling direct integration into existing scavenge circuits without adapter fittings. Black anodized construction provides corrosion resistance in demanding environments where continuous oil recirculation occurs.

Scavenge filtration is critical in high-performance and competition engines where oil returns from the pan must be filtered before re-entering the pump. The -16 AN port sizing ensures adequate flow rates for systems engineered with this specification, preventing backpressure that could compromise oil return. The compact 3.9 x 1.65 x 8.05-inch profile and 0.44 lb weight make this filter suitable for tight engine bay installations common in race cars, marine applications, and vintage hot rods. Aluminum construction keeps overall system weight minimal while maintaining structural integrity under pressure cycles.

This filter serves builders and owners of custom-built engines, LS swaps, carbureted performance motors, and racing powerplants where factory oil systems have been upgraded or redesigned. Drag racing, circle track, and street performance applications frequently require standalone scavenge filtration to extend oil life and protect pump internals from debris circulated through return passages. Direct -16 AN connections eliminate the need for adapter fittings, reducing leak points and simplifying plumbing in complex engine bay layouts. Peterson Fluid is recognized in the racing community for producing filtration components that meet OEM performance standards while supporting aftermarket system design.
