Review on Uni Filter NU 4109ST 2 Stage Air by John Wright

Using this air filter, our team found that our motorcycles are running smoother and have improved performance. We are impressed with the ease of installation and high-quality construction. The two-stage filtration system ensures our engines are protected from dirt AND debris .The only con we have experienced is that it is slightly more expensive than other options on the market. Overall we highly recommend this product for anyone looking to improve their motorcycle's air flow..
