DUOOK 2-Pack Outer & Inner Air Filter for Kawasaki & Kohler Engines | Replacement for 11013-7044/11013-7019, AF25552/AF25551, 25-083-01-S

Overview

Meet DUOOK's 2-pack Outer and Inner Air Filters, designed to fit a wide selection of Kawasaki and Kohler engines. Rather than a one-model-only part, this kit aims to simplify replacements by covering multiple OEM numbers and model families. The result is a straightforward way to refresh the air path without hunting through catalogs. Handling the filters feels like a simple act of maintenance—compact, sturdy components that become part of a clean, well-kept engine bay.

In practice, you might notice the air filter assembly feel more purpose-built when you handle it—sturdy edges, a clean, tight fit, and an unmistakable scent of new filtration material. The inner and outer filters are designed to work together, filtering air as it moves toward the engine and helping keep contaminants at bay. With two filters in each pack, you’ll have a ready replacement for upcoming service windows and routine upkeep.

The DUOOK filters offer a practical, no-nonsense option, presenting an easy upgrade path that fits multiple machines without compromising the feel of a proper installation. The packaging clearly indicates the model families and compatibility so you can verify fitment at a glance.
