How to seal a hole without a welder?

[LPlates]

Hi. I've searched the net, but I keep getting the wrong results.

Wife has treated me to an intercooler for the car (lucky me (what's the catch? Dunno yet)). But shes managed to order technically the wrong one. I've emailed the company about the missing blanking plate, but I'm wondering if I can save myself some grief/wait? Am curious how said plate works considering theres only one bolt hole for the sensor

Thanks

I would just get and fit the appropriate sensor as a blank.

Sensor most likely has an o-ring to seal it.

Unless you have access to a lathe or some handy friends i would take the advice in the post above and use a sensor as the plug.

Presumably it’s for an intake air temperature sensor like this or similar:
