Twin Air Standard Air Filter - Beta 158029

• 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
