2023½-25 Duramax MAP Relocation Kits

Protect your 2023½-2025 Duramax 6.6L MAP sensors from dirty exhaust gas and sticky oil buildup with Banks’ MAP Sensor Spacer. They safely relocate your sensors out of the way of this contaminated air stream. The cleaner the sensor, the more accurate its measurements will be. A clean sensor results in more power and better fuel economy.

Beginning in mid-2023, GM separated the MAP sensor into two sensors: a temperature sensor located in the former MAP sensor position and a pressure sensor located in a new lower position. Check to ensure you have two sensors on the cast aluminum intake manifold. If you already have installed the Banks Upper Sensor Relocation Kit, please purchase the Lower Sensor Relocation Kit.
