MOJIOO Air Filter Kit — 4-Piece Inner & Outer Replacement for Donaldson/Kohler Cross-Reference, Direct-Fit OEM Match

MOJIOO 4-piece inner and outer air filter set replaces Donaldson P821575 / P822858 and Kohler alternatives to restore airflow and protect engines from dust and debris.

This MOJIOO replacement kit includes two inner and two outer air filters made to match OEM fit and filtration profiles used across many Kawasaki, Kohler and John Deere applications. Designed as a direct-fit service kit for common part numbers (11013-7044, 11013-7045, M131802, M131803 and related cross-references), the set helps maintain engine performance, extend component life and simplify routine maintenance for lawn tractors, zero-turn mowers, commercial turf machines and small industrial engines.

Which engines and machines will these filters fit?

The MOJIOO kit is cross-referenced to a wide list of OEM numbers and fits numerous Kawasaki engines (FX-series and FH/FD series), Kohler model ranges and many John Deere lawn tractor and commercial units. Compatibility covers equivalents to Donaldson and Kohler part codes used across residential and commercial equipment.

• Cross-references: 11013-7044, 11013-7045, 25 083 01, 25 083 04, M131802, M131803 and more
• Kawasaki engines: FX651V–FX1000V and multiple FD/FH series models
• John Deere: Z-series zero-turns, compact utility models and many riding mowers listed by OEM codes
• Kohler: CH and CV series compatibility across 16–27 HP ranges and many turf machines

How do these inner and outer filters improve engine protection?

Using both inner and outer elements ensures staged filtration: the outer filter captures larger debris while the inner element provides a finer final barrier. Together they reduce particle ingress to the intake, helping keep carburetors, injectors and cylinders cleaner between service intervals.

• Outer element traps leaves, grass clippings and large dust
• Inner element captures finer particulates that harm engine internals
• Designed for balanced airflow to avoid unnecessary restriction
• Materials matched to common OEM media for reliable performance

What are the practical benefits of choosing this MOJIOO replacement set?

This set provides immediate, cost-effective replacement parts so you can complete a full air filtration service in one purchase. The filters are made to fit standard housings and replace multiple OEM numbers, reducing downtime and inventory complexity for homeowners and service shops alike.

• Four pieces (two inner + two outer) to service two filter housings or keep a spare pair
• Direct-fit dimensions minimize installation time with no modifications
• Bulk compatibility across brands reduces part lookup and stock needs
• Economical alternative to buying OEM elements individually

How should I install and maintain these filters?

Installation follows the same steps as your original elements: remove the housing cover, replace outer and inner elements in the correct order, reseal the housing and check for proper seat and clamp engagement. Inspect the filters at every oil change or more frequently in dusty conditions and replace if the media is clogged or damaged.

• Remove housing cover and clean loose debris before installing new elements
• Install outer element first, then inner element, ensuring proper orientation
• Check gaskets and clamps for secure sealing after reassembly
• Replace filters when visibly dirty, torn or per manufacturer service interval

Who is this for: This MOJIOO set of four air filters is intended for homeowners, landscapers and small commercial maintenance teams who service Kawasaki, Kohler and John Deere powered equipment. It’s especially useful for anyone who prefers to keep spare elements on hand, services multiple machines, or needs a cost-effective, direct-fit replacement that matches common OEM part references.
