The AEM 1 BAR (15 PSIa) stainless sensor kit includes a stainless-steel PSIa pressure sensor, connector and pins, plus 1/8 in. NPT to -4 and to 3/16 in. barb adapters for manifold-pressure reference use. Stainless housings resist automotive fluids and AEM states these sensors are accurate to within about 1% of full scale; a PSIa sensor reads roughly 14.7 PSI at sea level when exposed to atmosphere.
