Duramax MAP Relocation Kit: 10-Minute Install
Merciless Racing shows how easy it is to install a MAP Sensor Relocation Kit on his 2017 GMC Sierra 2500HD. This kit comes with everything you’ll need for this simple upgrade that moves the MAP sensor out of the flow of the engine’s sooty and oily intake flow.

After cleaning his dirty MAP sensor with the proper cleaner (don’t use brake cleaner). The installation is clean, and it took him around 10 minutes from start to finish. “It won’t get clogged up. I don’t know how much of a difference it’ll make in performance, but if it keeps the sensor clean then why not?”
