Intake retrofit in progress for our XKR!
Maybe I'm being a little slow... I see what you mean but can't find anywhere to log this. Ssd and other adapters all read absolute atmospheric pressure sensor only

What is relevant for forced induction is intake air temperature. If you don't have cold air intake (not sure about XKR, F-type has it) then there are performance gains to be had.

When I looked at this I was thinking about adding a 1" ID hose from air box to air box to help balance the pressures to the MAF. I also think the larger restriction is where the tubing goes over the valve cover. Using a manual manometer you should be able to probe each tract looking for vacuum measured in inches of water column.
Intake restriction is relevant for a naturally aspirated engines. For a forced induction (i.e. supercharger) all your are doing with intake mods is introducing more dust and increasing chances to suck in water going through deep puddles.

And how exactly you figured I would get more dust in using larger size factory filters?
