The Twin Air Air Filter, manufacturer part number 153901 and vendor part number 715-3901, is designed for reliable filtration and airflow on 1987–1992 Suzuki LT250R Quadracer models. Its thick, flat foam sealing ring creates maximum contact with the airbox while functioning as a breathable gasket, helping support consistent air passage and engine performance in demanding riding conditions.
The filter uses a dual-layer, open-pore foam construction. The coarse outer foam captures airborne dirt, grime, and sand, while the fine inner foam provides a second filtration stage to trap smaller particles without unnecessarily restricting airflow. Its greaseless sealing design simplifies installation and helps maintain a dependable seal around the airbox.
Feature: The specially formulated adhesive is designed to withstand repeated cleaning, including cleaning with harsh solvents or gasoline when used according to proper service procedures. The filter is slightly smaller than the original equipment filter to increase air space and circulation around the filter, helping promote efficient intake airflow.
Fitment: Fits 1987, 1988, 1989, 1990, 1991, and 1992 Suzuki LT250R Quadracer models. Confirm vehicle application before installation and follow the filter manufacturer’s cleaning and servicing recommendations.
