Over on AULRO.com a friend is detail the rebuild of a 2010MY Puma. One of the things he has found is this "Hiclone like" restriction on the inlet side of the air filter box.

You do indeed have to be a member to see it. I have known of individuals purchasing and even manufacturing their own vortex generators for the input side of the airbox. It is supposed to increase fuel burn efficiency whilst improving air intake characteristics. Didn't realise they were 'standard issue' on the Puma though. If you're removing it it may mean that your engine will run a little hotter and the engine parameters (MAF etc.) may be affected. Your ECU is also set up for standard intercooler size, MAF and a multitude of other 'standard set up' figures.
If you don't need to remove it my advice would be not to. It is there to increase airflow by speeding up the airflow turning it into a spiralling vortex. Hope this helps.  If you go through life with your head in the sand....all people will see is an ar5e!!

As explained it was on the inlet side of the filter, the filter having more air forced upon it will naturally filter more air not block it! My mate made one out of aluminium for his Suzuki in a lunchtime and that hasn't got a turbo fitted! It could also be a design feature to prevent the air from stalling at the box as there would be a pressure reduction going from the smaller pipe into the larger box perhaps?! Who's got an 'A' in physics????
I can't think of any other explanation for the thing that is depicted above! Can you? Cetainly looks like a vortex generator to me! Did a bit of digging and came up with this, you may understand it better than my explanation...some people even fit two of the things, one pre turbo as you suggested: http://www.hicloneqld.com/products.html If you go through life with your head in the sand....all people will see is an ar5e!!

Someone installed 2 ThrustMax units in his Disco1 Tdi and found he could now get into his steep driveway when previously he needed low range.

aye up Derek,the inner filter on your friends air box is only on Aus export models,the reason for it is to keep Kangaroo's and Koala's from jamming the turbo
there thats that sorted 2.4 90 XS

I have to go with roel on this one......
K9F, what you say is 100% correct...... BUT........ there is no point creating a vortex Before the air passes through a pannel filter as the vortex will be lost as it passes through the element....... if it was fitted between the intercooler and the inlet it would work as described above. It is like a chick on a Friday putting on make up on (creating a air vortex) and then having a shower (cleaning the air)....... pointless

P.S. I did get a 'A' in physics  |

If im honest to you all i wouldnt bother talking about it
First - k9 im surprised...shocked even that you didnt recommend a search (this has beend discussed before) 
Second the vortex thing most people say rubbish...but who cares its part of the vehicle for us so it either works or is there fore another reason...but its still there Mike |

there might be good reason for the vortex as I understand it this is most helpful before a corner / right angle in the air path / ducting

Morning all,
While I was at uni I had to do some CFD/FEA as part of my course. Now I just happened to choose to model and analyse a Hiclone 
So although this may not mean anything to sum here are some screen shots of what happens when a Hiclone is used in an air intake. Click image to enlarge Click image to enlarge Click image to enlarge Click image to enlarge Click image to enlarge The affects will be gone once the air has passed through the air filter but it would mae the air hit the filter at a slightly faster rate. Really the best places for a Hiclone style device would be before the turbo (4-6 inchs), before the intercooler, after the intercooler and it might be an idea to have in a snorkel to increase the air speed for the longer distance between the air intake and the filter.
