Mild Steel M18X1.5 Thread Bung and Plug Kit – 3735

What O2 sensors does this work with?

• It has an M18 x 1.5 thread that is pretty much an industry standard. This bung and plug will work with all Innovate Motorsports wideband systems that we sell.  It will accept Bosch LSU 4.2 and 4.9 widebands, NTK widebands, and most narrow band sensors as well. A few motorcycles and ATVs use a smaller thread.

Can I weld it to stainless steel?

• Welding mild steel to stainless is a bit harder than welding it to mild steel, but a competent welder should have no problem.
