M18x1.5 O2 Sensor Weld Bung Nut — 304 Stainless, 4-Pack

Weld-in bungs for mounting an oxygen sensor into custom or repaired exhaust pipework.

• 304 stainless steel — resists heat and corrosion in the exhaust stream.
• M18 x 1.5 thread — the standard size for most factory lambda sensors.
• Notched base — seats cleanly against curved pipe for a tidy weld.
• Four per pack — enough for a full multi-sensor build.
