The MIKUNI Performance filter assembly is a clamp‑on, round air filter designed for street‑oriented motorcycles equipped with HSR42, HSR45, or HSR48 carburetors. Constructed from pleated cotton gauze, the filter delivers consistent airflow while trapping particulates, and its 3.00 in. inside diameter matches the OEM intake dimensions for a direct, bolt‑free replacement. The unit is finished in a durable black base with an optional red accent, providing a clean visual integration with most sport‑bike fairings.
Engineered as a direct‑fit, one‑piece replacement, the filter’s pleated media maximizes surface area to reduce pressure drop and maintain optimal engine performance under a variety of street riding conditions. The clamp‑on style simplifies installation, requiring only a secure fit around the intake without additional hardware. Each filter is supplied individually, ensuring that riders receive a ready‑to‑install component that meets the original specifications for fit and function.
