Air Filter Connector

Any idea what this second small pipe is for on the 200Tdi air filter box?

The photo shows both my old knackered one and the replacement one, which has an additional sticky-outy bit.

Looks like some kind of mod, can’t think what it could be for

I've seen it on a few now, having scoured the internet looking for a filter box in reasonable condition. Looks like it was probably on the early 200Tdi, but gone by the time mine was made (about November 1992)

Is the extra stub welded or bolted in?

Resurgam · Oct 19, 2023

It's not bolted in so I assume it's welded, but it's very neat. The end is threaded and there's a tiny bit that goes through into the box itself. Nitrous injection?

Bet you 50p that is for an air filter indicator, ie when the air flow gets restricted the filter pops up red.

Nitrous…mmmmm now there’s an idea I should ignore
