RUIANOMG Air Filter Replacement Set for Kohler Kawasaki John Deere — Inner & Outer Two-Piece, Restores Airflow

This RUIANOMG replacement air filter set (outer 11013-7044 and inner 11013-7045) restores clean airflow to compatible Kohler, Kawasaki and John Deere small engines.

If your mower, tractor or commercial small engine is running under load, a clogged or worn air filter reduces performance and increases wear. These two-piece replacements match the original outer and inner filter dimensions and media, giving reliable filtration for a broad range of Kohler, Kawasaki and OEM-equivalent engines. The kit lists cross-reference numbers so you can confirm fit with your equipment model or parts diagram.

How will these filters affect engine performance?

Installing fresh filtration helps engines breathe freely, which supports stronger throttle response and can reduce black smoke or rough idling caused by restricted airflow. Because this set replaces both inner and outer elements, it restores the two-stage filtration design many manufacturers use for long-lasting protection.

• Restores correct airflow for carburetors and fuel injection systems
• Reduces particulate ingestion to protect cylinders and valves
• Helps maintain power under load and during towing or heavy mowing

What machines and part numbers does this kit fit?

This RUIANOMG kit is made to be compatible with many Kohler and Kawasaki engines and with numerous John Deere lawn and utility models. The product replaces a wide list of OEM part numbers so you can match it to your equipment’s service manual or parts sticker.

• Kawasaki fitment examples: FX651V, FX730V, FH680V family engines
• Kohler examples: C940–C980, CH18–CH1000 and 16–26 HP series
• John Deere models: 1025R, 2025R, 2305, 3025E and several compact tractors and mowers
• Cross-references: 25-083-04-S, 841497 and many OEM numbers listed on the product

How do I install these replacement air filters?

Installation follows the same steps as the stock elements—open the airbox, remove the old inner and outer filters, inspect the housing and sealing surfaces, and install the new elements in the correct order. No special tools are required for most machines, but keep the work area clean to avoid contaminating the intake while the airbox is open.

• Remove airbox cover and note filter orientation before removal
• Clean dust and debris from housing and gasket surfaces
• Install inner element first, then outer element; reseal airbox and test

How long do these filters last and when should I replace them?

Filter life depends on operating conditions—dusty or sandy environments shorten intervals while light lawn use extends them. Inspect filters at each oil change or every 50 hours of operation; replace sooner if visibly soiled, damaged, or if engine performance suffers.

• Inspect at routine maintenance intervals or every 50 hours
• Replace immediately if media is torn, crushed, or soaked with oil
• Store spare filters in a dry, dust-free spot until needed

Who is this for: This replacement set is designed for owners and technicians who service compact tractors, zero-turn mowers, and utility equipment powered by Kohler or Kawasaki engines, plus anyone using John Deere models listed in the cross-reference. It’s suited to professional landscapers and DIYers who need an affordable, direct-fit alternative to OEM parts while preserving engine longevity and performance.
