Buy a multipack and be done with it. I use them quit frequently when doing exhaust.

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.

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.

Don’t waste your time, complete junk. Low grade alloy, threads warped terribly and galled after welding. Good thing I had others to complete the project.

Fits the requirement. Not much can go wrong with basically a solid piece of equipment,
