The UNI Filter NU-2235ST is constructed from a pleated, wool-based filter media that offers exceptional filtration efficiency. The pleats increase the filter's surface area, allowing it to capture more dust and debris before they reach the engine. This not only protects the engine from damage caused by dirt and debris but also ensures optimal engine running conditions.
The UNI Filter NU-2235ST is designed to fit securely in the factory airbox of the Yamaha YZ400, IT400, and YZ250 motorcycles. It comes with a specialized seal that ensures a snug fit and prevents air leaks, which can affect engine performance. The filter also features an oiled surface, which helps to attract and trap even the smallest particles of dust.
One of the unique features of the UNI Filter NU-2235ST is its easy-to-clean design. The filter can be washed and reused multiple times, saving riders the cost of purchasing multiple disposable filters. To clean the filter, simply remove it from the motorcycle, shake off the excess oil, and wash it in warm water with mild detergent. After cleaning, let the filter air dry completely before re-oiling and reinstalling it in the motorcycle.
The UNI Filter NU-2235ST is the ideal choice for riders who demand superior engine protection and performance from their 2-stroke motorcycle. Its high-quality materials, unique design, and ease of cleaning make it a must-have accessory for any Yamaha YZ400, IT400, or YZ250 rider looking to get the most out of their motorcycle.
