So I bought a test pipe from ebay and it comes with a O2 sensor hole. But I don't need it so I need a screw that will cover it up. It is M18x1.5 but Lowes and Home Depot don't have it, where can I get it?

Thanks

you can just leave the o2 sensor in there.
my test pipes came with the plus screw

any spark plug is the same thread pitch I believe

my civic dont got a o2 sensor there. mine is a dx hatchback so the test pipe is there to fill in the gap where a cat would be. thxs maybe i will just put a spark plug there

oil pan drain bolt. thats what 95% of ppl are using. they come in 18x1.5. Check out Autozone or Pep Boys or whatever local parts store you have.

no they dont use a drain plug bolt from a trans, their is a bolt that is sold for this reason, go to a muffler shop and tell them you need the plug for the o2 on the piping and they will sell you the "RIGHT" bolt you need
