JGR O2 Oxygen Sensor Stepped Weld Bungs (5 Bungs/5 Plugs) M18 x 1.5

just restocking.my shop..seems like a good part

These come chrome plated and must have the plating removed before I can weld them. This is irritating because it’s just another step I have to do for the product to work.

They're pretty. I can't tell if they're polished or chromed. I have not done any welding on these yet so cannot coment on that aspect What I can say is that they thread nicely and are about what I expected.

These have been great for the last few installations. Its nice that the plug is included so if you need to remove your O2 sensor you can just add the plug that is included and no leaks.

choice to use from three styles on hand to flux and arc stick install (Mazda Miata downpipe). Deep step, Chrome finish, good choice for me.

They weld fine, just grind off the chrome first or don't breath the fumes! Recommend you move on and look for stainless if you don't want rust.

Seem to be very nice quality. Ordered for customers vehicles for a wideband. I dobt like giving them my wideband. They can get there own.

Doing custom exhaust systems these are good to have on standy especially stainless steel
