Awesome product!
Every 5K to 6K miles I have had to clean the MAP sensor on my 25’ GMC Duramax due to soot buildup. Just over 9K miles so far and no problems! I know its going ti happen but hopefully a much longer time in between!

SDual MAP Sensor Relocation Kit - Winner
Cleaned up my sensors after some aggressive shifting 13k miles into a new vehicle. 2026 chevy 2500 6.6L L5P. Running smooth as can be now and will monitor cleanliness between oil changes for improvement. Install was straight forward though the video instructions outdated for the latest generation L5P.

Map sensor kit
Hopefully this item will buy more time between cleanings of the two map sensors. The sensors were sooted up and I’m surprised I didn’t throw a code. Unsure if this will effect my warranty.
