This is my first turbo car so I'm not sure if I'm describing this correctly. But dead center of the intercooler is that small box that looks like a sensor. I bought my 2020 1.5T yesterday slightly used but notice today it just didn't look right. So I pulled up pictures and it seems like there was a cap that goes over it to cover the screw/bolts and all. Where can I buy a replacement and what is it actually called?
