Indmar MAP Sensor - Chevrolet 5.7/6.0/8.1 Manifold Pressure

Restore smooth performance and reliable engine management with this Indmar MAP (Manifold Absolute Pressure) sensor for select Chevrolet-based Indmar marine engines. The MAP sensor measures intake manifold pressure and sends the signal to the ECM/PCM to help calculate correct fuel and ignition timing. A failing MAP sensor can cause hard starting, rough idle, hesitation, poor acceleration, rich/lean running, and reduced fuel economy—making this a key part to replace during troubleshooting or tune-up.

Designed for use on some 5.7L, 6.0L, and 8.1L engines, this sensor features a sealed pressure port with an O-ring for a secure fit and dependable readings in demanding marine environments.
