Disco dont know, what on earth do these do?

It was a while ago this was in for air conditioning problems and no one knew what these "bits poking out of the inlet pipe" were for.

Pretty sure it was a diesel I dont know marks of discovery models.

Its freelander thingy not a disco ref the inlet there are flaps inside to adjust air flow at different RPM's

Yes you are correct it was a freelander. well i guess someone at LR thought it was important.

Thanks

I think its to do with noise, ie tuning the noise out, fingers on a recorder type thing, lots of cars have them with just a go nowhere piece of pipe randomnly placed in the trunking somewhere

That was the first thing that I thought of, "tuning pipes". Nothing to do with the tuning of the engine in the expected fashion of fuel and air mixture, but tuning of sound to reduce/remove resonances within the air ducting and also by doing that reduce the possibility of turbulances in the airflow in the ducts.
