That can become a problem when you add a wideband for tuning, build a turbo conversion, change the downpipe, or need to move the lambda sensor into a better position.\u003c\/p\u003e\n\u003cp\u003eA weld-in lambda sensor nut lets you add a proper threaded port exactly where it is needed. The Exoracing adapter is machined from 304 stainless steel and uses the common M18x1.5 oxygen sensor thread, making it suitable for many narrowband and wideband sensor applications where the sensor also uses M18x1.5.\u003c\/p\u003e\n\u003cp\u003eThe machined collar helps the adapter sit neatly in the drilled hole before welding. Once installed correctly, it gives the sensor a strong, serviceable threaded mounting point in the exhaust.
