BOLD MAGENTA part numbers are new for 2027 PARTS-UNLIMITED.COM 2027 | SNOW EXHAUST EXHAUST 472 MUFFLER SENSOR ADAPTER FOR SKI-DOO E-TEC MODELS •Sensor adapter solves peak rpm loss problems •Aluminum finned design dissipates heat to aid in cooling the sensor •Adapter moves the sensor out of the extreme heat inside the muffler, allowing your machine to hold maximum rpm all the time • Threads into muffler, then simply thread the sensor into the adapter • Will not work with the stock muffler, only aftermarket mufflers NOTE: Adapter will cause the sled to run leaner.This is necessary for models which lose peak rpm because the sensor reads too hot.We do not recommend running this adapter unless you notice a problem with your sled.
