- Reduced Soot Buildup: By moving the sensor out of the direct intake path, the accumulation of performance-hampering soot is significantly minimized.
- Elimination of Routine Cleaning: Say goodbye to the messy and time-consuming task of regularly cleaning your secondary MAP sensor.
- Extended Sensor Lifespan: With less exposure to harsh contaminants, your MAP sensor is likely to maintain its accuracy and functionality for a longer period.
- Maintained Optimal Performance: Accurate MAP sensor readings are vital for proper engine management, ensuring your Duramax continues to deliver the power and efficiency you expect.

Imagine a future where you spend less time wrenching and more time enjoying the robust power of your 2024-2025 L5P Duramax. The factory placement of your secondary Manifold Absolute Pressure (MAP) sensor directly in the intake airflow creates a significant and recurring maintenance headache. As your engine works hard, soot and particulate matter accumulate on this crucial sensor, leading to inaccurate readings, potential performance issues, and the frustrating need for frequent cleaning or even replacement. This isn't just inconvenient; it can impact your engine's efficiency and longevity.
Introducing the Fleece FPE-L5P-MAP-SPR-24 Secondary MAP Sensor Spacer, a smart and simple solution engineered to address this very problem. This innovative spacer strategically repositions your secondary MAP sensor away from the direct onslaught of the intake air stream. By creating a slight offset, the Fleece Performance spacer dramatically reduces the amount of soot and debris that can accumulate on the sensor over time. This thoughtful relocation translates into tangible benefits for your Duramax:
