Don’t suppose anyone has a spare 4.2 supercharged intake they can measure? I would like to know the external diameter of the long pipe that runs from the air box plastics to the elbow I need the diameter of the elbow end circle?

Thanks! Current stable:

I have to take mine apart, just waiting for a little better weather so if no one else is able to respond then I can measure for you.

I took this from the manual can you clarify exactly what you want measured.

Thanks the end of 1 not connected to the air box thank you Current stable:

Hopefully this will help...
Sorry they are upside down, but nothing I could do following stans recent post on how to rotate photos would work. I even flipped them in Photoshop and uploaded upside down versions and they stayed upside down.

He wants the other end diameter, ie the inlet of the throttle body, call up a parts stockist may be the best bet

oh ok the Throttle body itself, not gone that far yet, just making my own smoke generator to find my leak, that may cause me to have to dismantle further, if so then I will measure. Range Rover 4.2 Supercharged 2006

Id estimate at 100mm but that is just a guess.

I thing its 89mm but not sure yes the other end please if you get that far  Current stable:

I spent a bit of time on this today....

As I cannot do a smoke test yet I thought I could just quickly remove the Throttle Body Intake as its only held in by the rubber collar connecting it to the Throttle Body, unfortunately even with a large pry bay I cannot get it free from the collar.

So it will have to wait for me to complete a smoke test, if that shows that the collar is faulty then I will be happy to cut it off and fit a new one. Range Rover 4.2 Supercharged 2006

I think there is a nut underneath it in the middle too to stop it moving did you get that off? then it should just need the jubilee loosening... Current stable:

I cannot see any nut and its not in the manual so do you know exactly where it is and I'll have another go. Jubilee clip is loose it just feels like the rubber has stuck to the casting and I really do not want to do any damage if I can avoid it. Range Rover 4.2 Supercharged 2006

if you look at that bottom picture you posted you can see a black circle grommet if you can you can pull the intake towards you to gt it out the grommet then you should be able to wiggle it out the back... now iirc I couldn't get it out the grommet and the grommet is on a little bracket with an 8mm nut or bolt I think so I loosed that off and it all came out... I may be making that nut bolt bit u but I seem to remember it fairly clearly  Current stable:

Ok I'll have another look, certainly there was not enough movement to slide the grommet off the spigot but if its held on with a nut then I will remove that.

Fingers crossed it won't rain tomorrow. Range Rover 4.2 Supercharged 2006

Had a look at RainAlarm and it showed a gap so popped out and sure enough there is a screw holding the spigot on, so many thanks for pointing that out, I don't think I would have found it. Difficult to get at with my sausage fingers and could not get a ratchet on it so open ended spanner one flat at a time.

It was still a struggle to remove the Throttle Body Intake but I hope the picture helps and that its what you are looking for.
