2017-2026 Duramax Edge Pyrometer Adapter (L5P-EXH-A177)

Note: To use this adapter, make sure your tuning turns off the factory EGT protection monitors.

If you're using an Edge CTS2 or CTS3 monitor on your 2017–2026 L5P Duramax, you'll know the factory EGT thread pattern is unique. Our L5P EGT Probe Adapter directly replaces the non-fitting adapter included in the Edge kit. This threaded manifold adapter allows the probe to be installed in the exact location as the factory EGT sensor, ensuring a clean, perfect fit. Built from high-quality 304 stainless steel, it eliminates guesswork for a hassle-free, direct installation. Our adapter is the simple, correct, and cost-effective way to guarantee clean, accurate EGT data for your tuned or monitored L5P Duramax.
