Silicone Charge Tube (Lower) / ACE 900 Turbo durability kit 939 Piston KitThe factory Ski Doo 900 ACE Turbo charge tube has many flaws that make purchasing this silicone charge tube an easy decision! The factory charge tube is made from cheap plastic, is too small, and is known to crack. Our silicone charge tube has many key benefits. The larger volume works very well with higher boost pressures as the air does not bottleneck and create heat. The high quality t clamps and silicone seal up very nicely and wont leak.
