I messaged EUROAMP asking if they planned to do the LR4 naturally aspirated 5.0L V8 and this is what they replied:

Hi Robert,

We would like to, but the mold for that pipe is very hard to make since everything is one piece. There seems to be a lot more demand than expected, so we may develop them in the near future.

Regards,

Christian

Well, I drove over to EuroAMP and I did not return with the parts.

I looked at two sets of top/bottom front crossovers for the 2016.

This is my opinion...

I may be way too picky, but I was not pleased with the quality of the casting or the finish on the mating surfaces.
The female interior surfaces/transitions were sharp from the casting and the interior flow channels were not smooth at the transitions as they should be.
The male surfaces were sharp from the casting and chipped (sometimes badly), presumably in shipping.

It appeared to me that there were no finishing steps applied after the parts were cast.
It also appeared to me that the parts had been simply dumped loose in a box with no protection and then impacted each other during shipping, thus causing the chipping.

In my opinion if something as easy as shipping cannot be completed properly, and the castings leave sharp edges, then I lose confidence that the o-rings used are of good quality and I lose confidence that there is any quality control during manufacture.

I could have lived with the sharp edges from the casting, but I could not get past the chipped surfaces.

Would these work - sure.
But not for me...

If you go this route I would suggest purchasing o-rings of known quality.

Great notes tx. One thing I noted when I replaced mine was that the O rings had become very soft compared with new spares from LR.

The other thing that would make me pause is the type if alloy they have used. Different aluminum alloys in the presence of coolant when they start to leak past the o rings, which will happen eventually, can be very damaging indeed.
I’ve had this happen on Detroit diesel generators in the past and it’s been expensive to repair to say the least.

I spoke to Phillip at PalmBeach Rover Parts and he told me that the 3 part design in aluminum was an old Rover design that had been changed out to the new plastic 2 piece design and that when older vehicles come in they are updated to the new plastic parts. He did not have a good explanation of why, but from what he offered there did appear to be operating temperature related technical data behind the change, not just manufacturing cost concerns. He was unaware that either the 3-piece or the 2-piece designs were available in aluminum.

I need to do the pipes on my wife’s 2015 LR4 and I’m seriously looking at the aluminum pipes now that they’re available. It sounds like the two piece design is the way to go possibly with replacement o-rings. I don’t have time at the moment to do the work myself and the local shop I trust has no experience with aluminum tubes. They have been installing the upgraded Land Rover plastic parts and claim to have had zero problems with the re-design. They may be willing to do the job with the aluminum parts for me but without their normal warranties. It seems to me that eliminating the risk of a catastrophic coolant dump from those pipes would be a good enough reason to go aluminum.
