The UNI NU-3264ST Air Filter is a high-quality replacement filter designed to fit the factory air box of select Yamaha PW 50 motorcycles exactly like the original equipment filter. Manufactured by UNI and supplied under vendor part number NU-3264ST, this replacement air filter helps support dependable engine air filtration for off-road riding and routine maintenance.
Its unique two-stage design uses dual layers of foam that can be serviced separately, making cleaning and maintenance more convenient. The thin Ultra Seal base is engineered for durability and includes a built-in grease groove to help create a secure seal against the air box. This design helps reduce the risk of unfiltered air bypassing the filter during operation.
The UNI NU-3264ST is engineered for competition motorcycles and ATVs and is associated with factory-level off-road applications from Yamaha, Kawasaki, and Suzuki. It fits Yamaha PW 50 models from 1981 through 1990, offering a direct-fit replacement solution for riders who need a serviceable foam air filter for regular use or off-road performance applications.
