The Twin Air Pre-Oiled Air Filter is designed for reliable engine protection and consistent airflow on select Honda motocross and cross-country motorcycles. Manufacturer part number 150228X and vendor part number 715-0228X identify this replacement filter for the 2020 and 2021 Honda CRF250R and CRF250RX. The filter is pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco.
Its dual-layer foam construction provides effective filtration without unnecessarily restricting air passage. The coarse, open-pore outer foam captures airborne dirt, grime, and sand, while the fine, open-pore inner foam helps trap smaller particles before they reach the engine. The adhesive is formulated to withstand repeated cleaning, supporting dependable service over the life of the filter.
Designed smaller than the stock filter, this Twin Air model helps increase air space and circulation around the filter while maintaining a precise fit. Independent testing by a leading engineering laboratory in Germany identified Twin Air filter oil as a superior option for foam air filter applications. This filter is intended for off-road riding conditions and is a direct replacement-style component for compatible Honda models.
