Hi, you do have the pipe that feeds warm air into the airbox missing from the heatsheild at the front of the engine. Personally I wouldn't worry about it, all it does is duct some warmed up air from around the manifold to the airbox. I'm not too sure what the purpose of it is to be honest. I think in really really cold snowy/icey/foggy weather conditions you want slightly warmer drier air into the engine so somewhere that's frequently like that would need it. In the UK its seldomlyas bad as that. I don't have that pipe on my 1.4 and the one on my dads volvo is missing too.
If you undo the bolts that hold that thin metal shroud on you will also see that it has very little purpose.
See what other people think about it then make up your own mind, if it costs any more than a fiver I wouldn't even consider putting it back on...
