Description

Premium Washable Racing Air Filter – Fits 2.5" Filter Adapters for Go-Karts & Mini Bikes


Take your engine performance to the next level with our Premium Washable Racing Air Filter, engineered specifically for go-karts, mini bikes, and small engine racing applications. Designed to fit 2.5”(64mm) filter adapters—including most Tillotson HL and clone-style carburetor inlets—this filter delivers professional-grade airflow and protection for serious racers.


Unlike low-quality “washable” filters that rely on paper elements, our filter is built with high-performance cotton fiber media and deep, wide pleats. This advanced design provides maximum surface area for superior airflow, exceptional dust filtration, and cooler intake temperatures. The result is improved throttle response, consistent carburetor tuning, increased horsepower potential, and extended engine life.


Finished in a sleek blacked-out racing design with the embossed EC logo, this filter isn’t just built to perform—it shows you trust the power, performance, and durability of EC Products.
