Description
Direct carb mounting means zero airbox restrictions and measurable gains in throttle response and airflow efficiency. The K&N RC-1250 delivers genuine performance without the complexity of custom fabrication—just match your carburetor’s throat diameter and bolt it on. If you’re running a 57 mm carb throat, this clamp-on filter eliminates the factory airbox bottleneck and gives your engine the unrestricted breathing it demands.
