Product Description
Genuine GM 55567257 LS9 LSA ZR1 3-Bar MAP Sensor – Supersedes 12592525
OEM 3-Bar Manifold Absolute Pressure Sensor for Supercharged and Forced-Induction Applications
Monitor manifold pressure in a compatible forced-induction engine combination with Genuine GM 3-bar MAP sensor 55567257. This blue sensor is the current GM replacement for discontinued red MAP sensor 12592525 and is the original-equipment MAP sensor used with GM LSA and LS9 supercharged engines, including LS9-powered ZR1 applications. The factory three-bar pressure range supports readings up to 30 psi of boost, making the sensor suitable for compatible supercharged and turbocharged applications. GM 55567257 works with many factory PCMs and aftermarket EFI systems configured for this sensor; tuning and proper sensor calibration are required.
Key Features & Benefits
- Genuine GM Part Number 55567257: Manufactured as a Genuine GM component for the supported manifold-pressure applications. The current part number provides a clear reference when replacing the corresponding original-equipment three-bar MAP sensor.
- 3-Bar MAP Sensor Range: Designed to read manifold pressure in forced-induction engine combinations producing up to 30 psi of boost. This expanded pressure range supports compatible supercharged and turbocharged applications requiring more capability than a standard naturally aspirated MAP sensor.
- OEM LSA and LS9 Sensor: Used as the original-equipment manifold absolute pressure sensor on GM LSA and LS9 supercharged engines. This includes the supercharged LS9 engine installed in applicable Chevrolet Corvette ZR1 models.
- Factory PCM and Aftermarket EFI Compatibility: Compatible with many factory GM PCMs as well as numerous aftermarket electronic fuel-injection systems. The selected engine-management system must be configured and calibrated for the GM three-bar sensor.
- Updated Blue Replacement Sensor: GM 55567257 is the new blue sensor that supersedes discontinued red sensor 12592525. The superseded number remains included in the listing to help identify the corresponding GM MAP sensor replacement.
Notes
- Tuning and proper three-bar MAP sensor calibration are required.
