Hardware | Block off Kit Set YXZ1000R

The AIS (Air Injection System) Block Offs are designed to give you an accurate AFR (Air Fuel Ratio) reading when using a wide-band oxygen sensor to monitor AFR on the Yamaha® YXZ 1000R. Whether using an automatic tuner or monitoring the AFR, the AIS Block Offs eliminate the addition of oxygen to the exhaust system, creating a true AFR reading.
