Engine-ready filtration for John Deere and Kawasaki lawn equipment

The MOWFILL M115978 air filter kit is designed to replace multiple OEM parts while helping your mower breathe cleaner air. This kit includes one air filter and one pre-filter, crafted to fit a range of John Deere and Kawasaki engines. Built with dependable materials and precise sizing, it supports consistent airflow and protects the intake system from dust and debris during every pass across your yard.

With a focus on reliability and ease, this filter set aligns with OEM-inspired quality and ships in a way that makes storage straightforward. The result can be a smoother mowing experience, better throttle response, and less maintenance disruption on busy weekends.

Designed for a precise, factory-style fit

The filter’s exact dimensions are 3 5/8 in width, 6 3/4 in length, and 2 3/8 in height. These measurements help ensure a snug seal and efficient filtration without gaps that could let unfiltered air through.

Compatibility at a glance includes a mix of John Deere and Kawasaki models commonly found in residential and light commercial use:

• John Deere LX178, LX188 (and related LX series)
• Kawasaki FD501V, FD440 engines
• Other listed John Deere and Kawasaki models noted in the specification

What’s included and how it helps

• 1 air filter and 1 pre-filter — ready for immediate replacement
• Factory-grade quality that mirrors OEM standards, with separate packaging for easy storage

The included pre-filter acts as the first line of defense against dust and debris, helping extend the life of the main filter and protect the engine’s intake system. The separate packaging is designed for tidy storage in a shed or workshop, so you can keep spare parts organized and accessible.

Real-world use and potential benefits

In dusty, dry, or high-workload mowing conditions, clean filtration can support smoother starts and steadier throttle responses. The compact kit is easy to store in a toolbox or garage, and the clear labeling helps you identify the right replacement parts quickly. While the results can vary by usage, the setup is intended to offer a practical path toward better filtration, easier maintenance, and longer engine life with proper care.

Installation and care tips

During installation, ensure the seal sits evenly around the intake housing and replace the pre-filter at intervals that match your mowing schedule. Storing the spare kit in a dry place helps prevent contamination and preserves filter performance for when you need it next.
