3/8″ NPT Aluminum Weld-On Bung for IAT or CLT Sensor

Should I use this bung or the stainless steel bung?

• It depends on the intake piping material. Use this mounting bung if you are using aluminum pipe, and the stainless steel bung if using steel pipe. For plastic charge piping, you can use either bung and attach it with epoxy.

Do I need this if I am installing the sensor in a cast manifold or cast tubing?

• No, the bung is only necessary if you are mounting the bung in a thin walled surface that doesn't have enough thickness to cut threads into it.
