Repl Filter Element 100 Micron Pleated

The Peterson Fluid Repl Filter Element 100 Micron Pleated (part number 08-1900) is a return-line filter element engineered for dry sump oil systems. This 100-micron pleated stainless steel screen element removes particulate contamination from recirculated oil, protecting critical engine components in high-performance and racing applications where oil system cleanliness directly impacts engine longevity and reliability.

The 100-micron filtration rating balances flow efficiency with contamination removal, allowing adequate oil circulation while capturing wear particles, debris, and oxidation byproducts before they recirculate through the engine. The pleated design increases effective filtering surface area, reducing pressure drop and heat generation compared to flat-screen alternatives—a critical consideration in sustained high-RPM operation. The stainless steel construction resists corrosion and maintains structural integrity under the thermal and pressure cycling typical of performance engines.

This element is designed for Peterson dry sump oil tanks used in circle-track racing, road racing, off-road competition, and high-output street performance builds. Dry sump systems isolate oil in a dedicated tank and pump it through the engine and cooler on demand, allowing precise oil volume control and superior cooling—but the return line filtration becomes the final defense against accumulated contaminants. Regular element replacement maintains system cleanliness and extends engine service intervals.

Weighing 0.2 lbs with compact dimensions of 5.8 x 0.8 x 9 inches, this filter element is a direct fit for compatible Peterson tank assemblies. Verify fitment against your specific tank model before ordering. As a consumable wear item, stock spares for race weekends and regular maintenance intervals to ensure uninterrupted system protection.
