Twin Air Foam Air Filter 

• Twin-Air dual-stage filters are used by factory race teams and leading riders around the world
• Dual-bonded foam design removes even microscopic dirt particles, yet allows more air flow than regular "two separate layer" filters (flow bench tested)
• Flat foam sealing ring maintains a secure seal to the airbox, even in the worst riding conditions
• Twin Air filters run slightly smaller than stock, making them easier to change and increasing the dead air space around the filter for better performance

Now all customers can have the same factory service that top professional race teams and OEM customers have received for the last 10 years. Using their new state of the art filter oiling machine, each Twin Air filter is completely submerged in Bio-Oil and massaged to perfection to ensure that all pores are evenly coated. The filter is then placed in a temperature-controlled room to allow the oil to fully cure on the filter. The complete process provides maximum protection and maximum airflow. You just open the resealable bag and install, no mess, no fuss.
