156140 - Twin Air Standard Air Filter For Polaris Big Boss 500 6X6

Features: Twin Air dual-stage filters are the choice of top factory teams and riders worldwide. Dual-bonded foam design filters out even the smallest dirt particles, while allowing more airflow than two separate layer filters (flow bench proven). Twin Air filters are slightly smaller than stock to make them easier to change and to increase dead air space around the filter for better performance. Flat foam sealing ring securely seats against the airbox, even in the worst riding conditions. Comes with rubber fitting that eliminates the need for the stock airbox filter cage..
