Keep Your Duramax Sensor Clean And Your Power Consistent

If you have ever pulled a MAP sensor and found it coated in soot and oil, you already know how quickly performance can start to suffer. This PPE upper MAP sensor relocation block is built to solve that problem before it turns into something bigger. Designed for 2017-2026 Silverado and Sierra 2500HD and 3500HD trucks, it moves the sensor out of the direct path of dirty airflow. That means less buildup, more accurate readings, and a truck that continues to run the way it should. Additionally, cleaner sensor data helps your engine maintain proper fueling and response, especially when you are towing or putting the truck under load. It is a simple upgrade that works in the background but pays off over time. Installation is straightforward, so you can get it done without turning it into a full day project. If you want to stay ahead of common Duramax issues, this is one of those upgrades that just makes sense.

Precision Engineered Relocation Design For Reliable Sensor Accuracy

The PPE 115672017 upper MAP sensor relocation block is designed to improve long term sensor performance by relocating it away from contaminated airflow. It is CNC machined from 6061-T6 aluminum, which provides excellent strength and resistance to heat and corrosion. Additionally, the black anodized finish helps protect the surface while maintaining a clean appearance under the hood. By reducing exposure to carbon and oil deposits, the MAP sensor can deliver more consistent and accurate readings over time. This directly supports proper fuel delivery, boost control, and overall engine efficiency. The kit includes the necessary bolts and an O-ring seal to ensure proper fitment and sealing during installation. For 2017-2026 6.6L Duramax applications, this component helps maintain reliable performance without adding complexity to your setup.
