Missing bolt and air filter question:

[MrsWench]

Hello, new here. I am doing some basic maintenance items on my '12 Sonic LT hatch and I noticed I am missing a o2 sensor bracket bolt on the manifold heat shield and cannot find a replacement identifier for it anywhere. Is this something I have to order from the dealer? It is marked 1 in the attached diagram. I want to make sure I get the right size bolt.

Also, there is a secondary filter inside the engine air filter housing that is clipped to the lid and I would like to replace that as well and cannot find even a mention of it anywhere. I didn't think to take a picture when I had it open.

Any help would be greatly appreciated. Thank you!

Nah. It's all standardized threads. It doesn't bear a load so its just there to hold that cover on. You can get that specific bolt from a local junkyard. Or if you have that bolt #(4) that's on the other side, should be the same thread and size, take that to your local hardware store and buy whatever is closest in size with the same thread.

Fair point, thank you!
