Yes but I have worked with wind tunnels before and the the 'grid' would be a lot deeper, obviously the original pipe work takes it through a series of pipes and makes the flow nice and laminar. Similar to the intake for a fighter plane, we have to try and prevent flow separation and encourage laminar flow by changing the design of the intakes.
I think with a 45 or 90 bend there will be enough pipe length to bring the flow laminar rather than sucking from the edges of the cone filter. Will test when I get a chance and if there is a suitable sized piece of silicone laying around... I think Mr postman is bringing some 45mm but I'm not sure what the MAF diameter is on the 1.4 HDI so it will be pure luck if I have anything to go on there.
