Stainless steel lambda probe insert to weld

Stainless steel shouldered weld-on bung for a lambda, wideband or AFR sensor (ref. ISLI).

This stainless bung welds onto the exhaust to fit an AFR (air/fuel ratio) system and monitor engine mixture. Its standard M18 x 1.5 thread accepts most lambda and wideband sensors on the market. The shoulder makes it easy to position and weld onto the manifold, at the collector point where the cylinder runners meet.

Dimensions: body outer diameter 25 mm, diameter of the section inserted into the exhaust 21.90 mm, height of the inserted section 4 mm, overall height 14 mm.
