Default oxygen sensor thread size?

Does anyone know the thread pitch for a 12mm narrow band and 18mm wide band oxygen sensors so i can pick up some plugs for them? Waiting for the new Fuel moto headpipe for the 2010 2into1 on the glides and it does not come with the sensor plugs

Thanks for the pitch would you know the length off hand? I got Autotune coming with the Fuel Moto 2into1 headpipe and want to plug the 12mm narrow bands.

The plugs don't have to be too long. You can get a brass plug at a hardware store, or you can go to any muffler shop and get an actual 02 sensor plug, or you can actually buy 02 sensor plugs online that claim to be harley 02 sensor plugs. Here's an attached pic showing the size.

I was told Toyota oil pan drain plugs are 18mm 1.50 @4.00 Vs 18.00 at the bike shops. I just figured if i looked around i could find them cheap. I'm having trouble finding the 12mm 1.25s but i guess i can check the muffler shops. Have not had any luck at hardware stores.

You are correct, oil pan plug at auto store works fine and others have went this route. Have you considered throwing a 12mm spark plug in there? Would make a good conservation piece, hehe.

Just installed a Fuelmoto headpipe on a 2010. Very nice piece, welds were great. It came with 2 of the 18mm plugs as the pipe does have the 12mm in the stock position and the 18mm up by the heads in the pre-09 position and can be easily used by tuners.

What headpipe was that? Keith just told me the new 2 into 1 they are making up with no cat for the 2010 does not come with 12 or 18 mm plugs. Wonder why? Need the 12mm to block off the stock os holes and Autotune will go in the 18mm holes.

The part number for the Toyota truck oil pan drain plug is 90341-18016
They're only a couple of bucks a piece at the dealer. Be sure to use some anti-seize or maybe some red high temp silicone on the threads. There may be one avaiable, but they don't come with a gasket.
