MOWFILL Air Filter Kit Kohler 16 083 04-S & Bad Boy 063-5003-00 + Pre Filter

Overview

Upgrade your mower’s air intake with the MOWFILL air filter kit, designed to pair with Kohler engines labeled 16 083 04 and related variants, as well as Bad Boy 063-5003-00. This replacement set also includes the 16 083 05 pre filter for enhanced protection. Sized for ease of handling, the kit aims to simplify routine maintenance while supporting steady engine airflow.

Fit and performance go hand in hand. The air filter and pre filter are designed to fit a 4 inch width, 6 5/8 inch length, and 2 7/8 inch height, creating a secure seal that helps keep dust and debris at bay. The included pre filter offers an extra line of defense by intercepting larger particles before they reach the main filter, which can contribute to more consistent filtration during regular mowing sessions.
