The factory charge tube is made from cheap plastic, is very small, and bottle necks in the middle.  Whenever you bottleneck air, it makes that air hotter which is a huge problem when turning up the boost.  We see much cooler charge air temps when data logging with our charge tube vs the factory one.
This charge tube fits all 2016-2019 RZR XP Turbo Models, Turbo S 72" Models, & 2020 RZR Pro XP Turbo
Larger volume greatly reduces heat buildup in the charge tube for more consistent performance
Must have for anyone running 18+ PSI of boost
Charge tube will not fail like the cheap factory plastic one
Charge tube diameter is 2.25"
Aluminum dissipates heat and flows better than plastic or silicone
Bead rolled ends to hold even under high boost pressures
Much better sealing with high quality silicone couplers and T clamps
Side map sensor location allows better fitment of the sensor under the bed
Mounts easily and nicely in the factory location
We highly recommend this for anyone running our tunes, and especially level 3 & higher
For even better fitment, we recommend using these Longer Spark Plug Wires 
Made at the AA Facility in the USA
