Mysterious Pipes

[Tyre Tread]

There are 2 fixed pipes at the base of the plenum facing forward on the car that appear to be open to atmosphere. Anyone know what these are and if they should be conected.

There is a take off hose coming off the inlet manifold that's blocked off. Is this normal?

Thanks.

Not needed.

They would be connected to the cooling circuit on a Range Rover to heat the plenumn air supply.

Yes, both are normal. Range Rover and Land Rover used them to supply hot water to the plenum which TVR never used. The rubber pipe with a bolt in is a legacy from the Land Rover/ Range Rover too.
