What fluids can harm AEM sensors? What fluids are compatible?
All AEM pressure sensors feature a 360-degree welded stainless-steel wetted area. What this means in plain English is that they do not have any o-rings or gaskets that the fluid can come into contact with. No typical automotive fluid will harm these sensors. They are compatible with Gasoline, Methanol, Ethanol, Nitro-methane, Hydraulic fluid, Nitrous Oxide, Brake Fluid and Oil.
