S&B Lower MAP Sensor Spacer Kit for 2024-2025 Chevy Silverado / GMC Sierra Duramax L5P 6.6L

Lower MAP Sensor Spacer Kit for 2024-2025 Chevy Silverado / GMC Sierra Duramax L5P 6.6L

Prevent false MAP sensor fault codes and unwanted check engine lights on your modified 2024-2025 Duramax 6.6L with this MAP sensor spacer kit. Tuned diesel trucks running elevated boost levels can trigger the factory MAP sensor before the tune's boost target is reached - this spacer raises the effective ceiling to eliminate that issue. A simple, precision-machined solution for any modified diesel build.

Key Features

• Prevents false MAP sensor fault codes on modified 2024-2025 Duramax 6.6L running elevated boost
• Raises the boost threshold seen by the MAP sensor - eliminates CELs during hard acceleration
• Precision-machined aluminum construction with direct OEM-fit mounting
• Essential for tuned diesel builds exceeding factory MAP sensor calibration limits
• All installation hardware included for a direct bolt-on installation

Benefits

On tuned diesel trucks running boost beyond the factory MAP sensor's calibrated range, false fault codes and engine derate conditions are a common frustration. A MAP sensor spacer is the straightforward, permanent fix - raising the sensor's effective ceiling so your tune can deliver its full potential without triggering CELs.
