Kohler engine oil filter set of 2 12 050 01-S — 32-micron media, anti-drainback & relief valve

Kohler 12 050 01-S set of two genuine OEM engine oil filters provide reliable particle capture and anti‑drain protection for Kohler and compatible OEM engines.

These factory-packaged Kohler oil filters are designed as direct replacements for routine engine maintenance. Each filter uses a 32‑micron media to trap contaminants while an internal relief valve opens at 8–11 PSI to protect oil flow under cold starts or heavy contamination. The anti‑drainback feature helps keep oil in the engine during shutdown, reducing dry starts and wear on bearings and cam components.

How do these filters fit my Kohler or OEM engine?

The 12 050 01-S filters are made to Kohler’s original specifications for a straightforward swap when the old filter is removed. They come in factory packaging and include two identical units so you can replace filters on two machines or keep a spare on hand. Check your engine’s parts manual or existing filter number to confirm compatibility before ordering.

• Direct OEM replacement part number: 12 050 01‑S
• Pack count: Set of 2 for convenience
• Fits many Kohler engines and compatible OEM models—verify with engine model
• Factory packaging preserves part integrity until installation

What performance can I expect from the 32‑micron filter media?

The 32‑micron rating balances filtration and flow, capturing larger abrasive particles that can accelerate wear while maintaining adequate oil circulation for cooling and lubrication. This rating is suited to many small to medium displacement engines where oil flow is critical. It’s not an ultra‑fine fuel or hydraulic filter; it’s optimized for engine sump oil service.

• Particle capture: 32 microns for robust contaminant removal
• Maintains oil flow to protect bearings and moving parts
• Appropriate for routine engine oil service intervals
• Designed for durability under typical operating conditions

Why do the relief valve and anti‑drain feature matter?

The internal relief valve opens between 8 and 11 PSI to allow oil circulation if the filter becomes restricted, preventing oil starvation during heavy loads or cold oil conditions. The anti‑drainback valve keeps oil in the engine when it’s turned off, which reduces dry starts and prolongs component life. Together these features help maintain reliable lubrication across a variety of operating scenarios.

• Relief valve set to operate at 8–11 PSI for protected flow
• Anti‑drainback valve maintains oil in the engine at shutdown
• Reduces wear from dry starts and restricted flow events
• Improves reliability across temperature and load ranges

How should I install and maintain these filters?

Installation follows standard oil filter procedures: drain oil to the recommended level, remove the old filter, apply a light coat of clean oil to the new gasket, hand‑tighten the new filter, then start the engine and check for leaks. Replace the filter at the interval specified in your engine’s service manual or sooner under severe operating conditions. Dispose of used filters and oil responsibly following local regulations.

• Prepare: drain oil per engine manual before removal
• Install: lubricate gasket, screw on, hand‑tighten to spec
• Verify: run engine, inspect for leaks and proper pressure
• Service interval: follow engine manufacturer recommendations

Who is this for: Owners, mechanics, and fleet managers who use Kohler or compatible OEM engines and want a genuine OEM replacement filter that balances filtration efficiency with dependable oil flow. This two‑pack is ideal for routine maintenance, keeping a spare on hand, or servicing multiple small engines with a single purchase.
