Universal 12mm Motorcycle Air Filter, Mushroom Style High Flow Crankcase Vent

Meet the Universal 12mm Motorcycle Air Filter, a compact mushroom-style, high-flow upgrade designed to optimize your bike’s breathing. Built as a universal 12mm solution, this air filter fits crankcase vent ports and cold air intake paths, delivering cleaner air and steadier performance without a hefty price tag. Its straightforward bolt-on design means you can upgrade quickly and ride with confidence.

Designed to replace worn or restrictive stock filters, this filter helps your engine inhale more efficiently. The result is improved air filtration, enhanced throttle response, and a boost in horsepower and torque, along with better fuel economy compared to a clogged or aging filter. The fine mesh promotes smooth, laminar airflow while keeping hot under-hood air at bay, helping maintain power and responsiveness even in heat. The filter is washable and built to last the engine’s lifetime, so you can reuse it ride after ride with proper maintenance. Available in bold red or classic black to match your bike’s aesthetic, and designed for a simple direct bolt-on installation.
