Some vehicles feature an oil gallery test port, but not all. If there is a test port location on your vehicle - this information would be located in the owner’s manual. GlowShift’s Oil Pressure Sensors are ⅛ NPT, please ensure the thread size on your vehicle as additional adapters may be needed. You can also use an oil filter sandwich adapter (see in our accessory section)
GlowShift does not have a database with Test Port Locations or Sizes.
