Kohler Engine Oil Filter 52 050 02-S - 3-Pack Extra Capacity, Relief & Anti-Drain Back

High-capacity Kohler 52 050 02-S oil filter replacement (3-pack) engineered to protect and extend engine service intervals on compatible Kohler CH, CV, M, MV and K-series engines.

This three-pack of genuine Kohler 52 050 02-S engine oil filters is a factory replacement designed to deliver the fit, filtration and anti-drainback features expected for Kohler small engines. Each filter offers extra oil capacity, a relief valve and anti-drain back protection to help maintain oil pressure and lubrication during operation and shutdown. The filters are bulk packed for trade use or home workshops, and are matched to a long list of Kohler engine models — always confirm compatibility with your engine serial or model number before installing.

Which Kohler engines is this 52 050 02-S filter compatible with?

This OEM part covers many CH, CV, M, MV and K-series engines from Kohler. It fits a wide range of model numbers used in lawn tractors, generators and light commercial equipment. Check your owner’s manual or engine label to verify the exact part match.

• Compatible with CH11–CH15, CV11–CV22, M18–M20, MV16–MV20 and K582 engine families.

How does the extra capacity design benefit engine maintenance?

Extra capacity means each filter holds more oil and media, which can improve contaminant-holding capacity and slightly extend effective service life versus smaller filters. That helps engines run cleaner between changes, especially under dusty or heavy-load conditions.

• Greater media volume captures more particles before reaching bypass pressure.
• Relief valve at 8–11 PSI protects oil flow if the filter becomes restricted.
• Anti-drain back valve helps maintain oil in the engine during shutdown for faster initial lubrication on restart.

What are the physical dimensions and installation details?

These filters are built to Kohler OEM specifications for a direct fit. The dimensions and sealing surfaces match the factory requirements to ensure a leak-free connection and correct relief characteristics for the listed engines.

• Height: 3-1/8 inches; outside diameter: 3 inches.
• Seal outside diameter: 2-13/16 inches for accurate gasket seating.
• Relief/anti-drain features: relief pressure about 8–11 PSI and an anti-drain-back valve for startup protection.

Before installation, always consult your equipment’s owner manual for the correct oil type, torque specs, and replacement interval. Replace filters when oil is changed or sooner if your operating environment demands more frequent service.

Why choose genuine Kohler replacement filters over aftermarket alternatives?

Genuine OEM filters are engineered and tested alongside Kohler engines to match flow, relief settings and fit. That compatibility reduces the risk of leaks, bypassing or premature clogging that can arise from incorrect media or construction in some non-OEM options.

• Factory-specified filtration and relief characteristics for Kohler engines.
• Bulk three-pack provides value for professional shops and homeowners who perform regular maintenance.
• Genuine part number labeling and materials ensure consistent performance and warranty alignment.

If your equipment matches the listed models and you prefer OEM fit and filtration, the Kohler 52 050 02-S-3PK is a direct, dependable replacement option.
