The Twin Air sponge air filter represents a true innovation in the world of motorcycle performance, specifically designed to ensure optimal airflow and superior protection. With over 40 years of experience, this filter has been developed to tackle the challenges of sandy and gravelly terrains, where traditional filters often failed to protect engines.
The dual-layer design combines open-cell foam with a fine inner layer, capable of trapping even the smallest particles, ensuring that only clean air reaches the engine. The round shape of the filter has been optimized to increase airflow, while the micro-adhesion process has minimized seams, thereby increasing the filtering surface and further enhancing performance.
Made with non-bouncing, slippery foam, the filter is washable and reusable up to 50 times, offering excellent sustainability. Each filter is hand-assembled and tested to ensure a perfect fit, making it an essential accessory for motorcyclists looking to maximize the performance of their Tm Racing.
