This Boost/Vacuum "Absolute Pressure" Sensor is Ideal for measuring vapor (gas) pressures, from intake boost to crankcase pressure. The 50 psi pressure range is based on perfect vacuum (i.e., from 15 psi below atmospheric pressure to 35 psi above).
Warning: Last items in stock!
This sensor is marked "0-50psiA" to differentiate it from the standard 0-50 psi sensor (marked "0-50psiSG"), which does not measure vacuum.
KA pressure sensors are more robust than VDO-style pressure sensors, but they should still be isolated from engine heat and vibration whenever possible. It is compatible with all AiM MyChron, MXL, MXL 2, MXG, MXS, EVO3, and EVO4 automotive applications. 1/8 NPT male threads.
This sensor has the 719 (four-pin plastic push-on type) connector. Use a My Chron 719-719 Patch Cable (Part No. AIM-MC-211) to connect to any AiM MXL series, MXL2, MXG, MXS, or MyChron3 Auto dash except MXL Strada and XG-Log. EVO4 and XG-Log require a 712-719 Patch Cable (Part No. AIM-MC-210, sold separately).
