Product Description
Genuine GM ACDelco 55573248 LS3 1-Bar MAP Sensor
Bolt-In LS3-Style MAP Sensor for Naturally Aspirated Applications
Maintain accurate manifold pressure readings with this Genuine GM ACDelco 55573248 1-bar MAP sensor. Commonly identified as an LS3-style sensor, its bolt-in configuration makes it a popular choice for naturally aspirated engine combinations using compatible aftermarket intake manifolds.
Key Features & Benefits
- Genuine GM ACDelco Sensor: Manufactured as a genuine GM ACDelco component rather than a lower-cost aftermarket substitute. Part number 55573248 provides the original-equipment reliability and accuracy expected from a sensor used in compatible factory and aftermarket engine combinations.
- 1-Bar Naturally Aspirated Design: This 1-bar MAP sensor is intended for compatible naturally aspirated applications. It provides the manifold absolute pressure signal required by the engine-management system without introducing an unverified aftermarket sensor into the combination.
- Bolt-In LS3-Style Configuration: The LS3-style bolt-in design is commonly required by compatible aftermarket intake manifolds. Its retained mounting configuration secures the sensor to the intake manifold in applications designed around this specific MAP sensor style.
- Accurate Manifold Pressure Signal: The MAP sensor supplies manifold pressure information used by the engine-management system. Choosing the genuine GM component helps avoid the inaccurate readings and premature failures that can occur with some cheaper aftermarket replacement sensors.
- Factory and Aftermarket Applications: GM originally used this sensor across multiple gasoline V8 Chevrolet, GMC and Pontiac models. It is also a popular option for compatible engine swaps and naturally aspirated builds using an aftermarket manifold that accepts a bolt-in LS3-style sensor.
