UNI UP‑4112AST Air Filter – 1" Clamp‑On Angled Flange – Honda Z50 / XR50 / CRF50 (1979‑2020) – USA Made

The UNI UP‑4112AST Hi‑Flo Angled Air Filter is a premium clamp‑on performance filter designed for Honda Z50, XR50, and CRF50 models running stock carburetors without the airbox. Its 1" (25 mm) inside‑diameter flange and compact body make it a perfect fit for pit bikes, minis, and vintage Honda 50cc machines.
The angled flange allows the filter to be rotated away from aftermarket exhaust headers, preventing heat damage and improving airflow routing. Built with a durable urethane mounting flange and UNI’s legendary dual‑stage foam, this filter delivers maximum filtration, excellent airflow, and long service life. Fully washable and reusable.
Proudly Made in the USA.
