Product Description

The K&N YA-3215 air filter is engineered as a high-performance replacement for stock air filter elements on a range of modern motorcycles - notably Yamaha's YZF-R3 and MT-03, and compatible Suzuki 125 / 150 class bikes, depending on regional fitment. Its pleated cotton gauze media significantly increases intake airflow relative to typical disposable filters, which can improve throttle response and overall engine performance without sacrificing filtration quality for street or light-sport use.

Designed for direct drop-in installation into the OEM airbox, YA-3215 ships pre-oiled and ready to install - no custom fabrication or modifications are required for correct models. For maintenance, simple cleaning and re-oiling per K&N instructions restores peak performance. With durable construction, repeated serviceability, and proven airflow performance (≈ 120.6 cfm @ 1.5 in H2O), this filter is ideal for riders who want a balance of performance, protection, and long-term value from a maintenance-free air filtration solution.
