The Twin Air 151801 Air Filter is designed for dependable engine protection and consistent airflow in 2003, 2004, 2005, and 2006 Kawasaki KFX 400 applications. Its thick, flat foam sealing ring creates maximum contact with the airbox while functioning as a breathable gasket that supports increased air passage. The filter is manufactured for reliable fitment and durable performance in demanding off-road riding conditions.
Its dual-layer, open-pore foam construction captures airborne dirt, grime, and sand before contaminants can reach the engine. The coarse outer foam traps larger particles, while the fine inner foam provides a second stage of filtration for smaller debris without unnecessarily restricting airflow. Twin Air’s slightly smaller-than-stock filter design helps increase air space and circulation around the filter, supporting efficient intake performance.
The exclusive adhesive is formulated to withstand repeated cleaning, including cleaning with harsh solvents or gasoline when used according to proper maintenance procedures. This makes the Twin Air 151801 a practical replacement air filter for riders who need reusable filtration and consistent sealing during regular service intervals. The greaseless sealing ring simplifies installation while helping maintain reliable contact between the filter and airbox.
