Description
Description
This plug-and-play delete plug replaces a failed muffler temperature sensor on 2019 and newer Ski-Doo and LYNX Gen 4 and 5 snowmobiles, sending an optimal temperature signal to the ECU so the sled keeps running at full power instead of dropping into limp mode. It installs without splicing or cutting, letting you bypass a bad sensor on the trail and ride back to the trailer, and it is built element-proof and dyno tested for high-performance setups including lake racing, nitrous, and turbo applications.
It fits 600 EFI, 600R E-TEC, 600RS, 850 E-TEC, 850 Turbo, and 900 Turbo models across MXZ, Renegade, Summit, Backcountry, Freeride, and NEO platforms.
