825-016 – Rotax Engines OEM Spin-On Oil Filter for 912 - 914 Engines
Available now on the Airparts.aero Marketplace.
Overview
The Rotax 825-016 is the genuine Original Equipment Manufacturer (OEM) spin-on oil filter, an essential and flight-critical component for the entire Rotax 912 and 914 series of four-stroke aircraft engines. This is not a standard automotive filter; it is a purpose-built filtration device engineered specifically for the unique high-RPM, dry-sump, integrated gearbox lubrication system of Rotax engines. It is designed to provide maximum protection against harmful contaminants while maintaining the precise oil pressure and flow rates required for these high-performance powerplants.
Key Features
- Engineered for Rotax Systems: Specifically designed to be compatible with the pressures and flow characteristics of the Rotax dry-sump lubrication system, which lubricates the engine, propeller reduction gearbox, and overload clutch simultaneously.
- Integrated Pressure Relief Bypass Valve: Features a built-in bypass valve with a precisely calibrated opening pressure. In the event of a completely clogged filter or extremely cold, thick oil, this valve opens to ensure a continuous, albeit unfiltered, supply of oil reaches critical engine components, preventing catastrophic oil starvation.
- High-Efficiency Filtration Media: Utilizes a high-quality, pleated micronic filter media designed to capture microscopic metallic particles from engine and gearbox wear, as well as carbon and other contaminants, ensuring the cleanliness of the lubricating oil.
- Robust Canister Construction: Features a heavy-duty steel canister and a robust mounting plate designed to withstand the high oil pressures and constant vibration inherent in Rotax engine operation.
- Direct OEM Replacement: As the genuine Rotax factory part, it guarantees the correct fit, performance, and quality required to maintain the engine's warranty and airworthiness. This part number supersedes the previous P/N 825-012.

- Rotax 912 UL (80 hp)
- Rotax 912 ULS / S (100 hp)
- Rotax 914 F / UL (115 hp Turbocharged)
Applications
The 825-016 is a critical component for maintaining the health and reliability of the Rotax engine:
- Engine Lubrication System: Its primary function is to remove harmful solid contaminants from the engine oil that circulates through the crankshaft, pistons, integrated gearbox, and overload clutch.
- Preventative Maintenance: Mandatory replacement item during every oil change to ensure the continued protection of the engine's internal components.
- Engine Health Monitoring: Inspection of the old filter's contents by cutting it open is a key diagnostic tool for detecting early signs of abnormal engine or gearbox wear.
Why Choose 825-016?
The Rotax 9-series engine has unique lubrication requirements due to its high RPM and integrated propeller reduction gearbox, which shares the same oil as the engine. The genuine Rotax 825-016 filter is specifically designed with the correct bypass valve pressure setting and flow rate to protect this entire system. Using a non-certified automotive filter can lead to incorrect oil pressure, potential oil starvation, and catastrophic engine and gearbox failure. For maintaining your Rotax engine to factory specifications and ensuring its legendary reliability, there is no substitute for the genuine Rotax OEM filter.

The integrated pressure relief bypass valve in the Rotax 825-016 is a non-negotiable safety feature. The Rotax lubrication system is a high-pressure design. If the filter media were to become completely blocked (e.g., from excessive contamination or from trying to push extremely cold, thick oil through it on a winter start), the oil pump would continue to try and force oil through. Without a bypass, the pressure could build to the point of rupturing the filter canister, leading to a complete and catastrophic loss of all engine oil in seconds. The bypass valve provides an alternate path for the oil to flow around the filter element directly to the engine, ensuring that lubrication is maintained, sacrificing filtration for continued operation in an emergency scenario.
Note: This is a flight-critical engine component. Installation must be performed in strict accordance with the current Rotax Heavy Maintenance Manual. Always apply a thin film of clean engine oil to the gasket before installation. The filter must be tightened to the specified torque of 20 Nm and properly safety wired.
