This is the first of many posts I hope as my wife and I are big volvo fans having just bought the 1997 V40 and about to buy a 2006 XC90.
A little background to my question. About 2 weeks ago the V40 bgan running very roughly in that each time I'd apply accelerator the engine would miss and splutter. I put this down to an air leak in the exhaust system that may be sending false readings to the fuel injection sensor. I finally got round to having a look and this is what I found - see photo below:

What is the name of this part with the broken port so I can order it? Here it is with respect to the engine.

The car is currently sitting on 160,000km so I guess this is a wear issue. Its simple to replace just hard to find the part when I'm not sure what it is. Thanks in advance for any suggestions.
