These intake boots are designed to work with the K&N RX-5090 Universal "X-Stream" Clamp-on air filter pods. They include tabs with a series of 6mm holes to allow them to be fastened to the bike in the manner of your choosing. These boots work with the stock rubber rings on the outside of the throttle bodies, where the original intakes are fitted. The air temperature sensor will need to be relocated, and a breather filter will need to be attached to the breather hose that goes into the airbox. See photo above.
