Boondocker Breathe Right™ Cold Air Intake for  Polaris AXYS 800 and AXYS 850 is the answer to frozen vents, baro-sensor trouble-codes, and poor performance on all Polaris AXYS snowmobiles (even naturally aspirated). The Polaris-OEM factory vents do not perform to our standards. They easily saturate with water and in most winter conditions, will freeze and prevent proper airflow, even on a stocker.
 
SUMMARY
Maximum performance comes from both a larger intake surface area and from using high-grade materials. Increasing the surface area allows for proper airflow in the most demanding conditions.
 
We start off with FrogSkinz-branded pre-filter material, which we have custom-cut for us at the factory. This material is the benchmark in hydrophobic pre-filter material. They simply won't absorb water.
 
The frame is constructed of aluminum for the ultimate lightweight performance part. The vents fasten to the snowmobile with four self-tapping screws, and can easily be installed in the trailer.
 
Installation is easy, with no drilling or cutting required! Simply install the four self-tapping plastic screws (per side) and you're ready to ride!
 
This is the best vent kit for Polaris on the market. The vents were designed to keep the stock filter installed. However, if you remove the stock vents, we suggest you keep them with the snowmobile in case you rip or tear your Agility vents during a ride.
