So, As
@KristinaM has described it's a 'PITA' to get installed. Rohan quoted me 6 hours to do the install here at his shop outside Melb.
He mentioned if I plan on tuning the ECU which he's cracked the firewall on then the intake's limiting factor is the narrow passage within the fender well. Since he's constrained the design to fit within Ineos' origional design, and no trimming the crossover tube within the fender is rather narrow and restrictive. Surprisingly so actually.
The Stainless model he offers into the fender is a 4.5" pipe,
HERE which is wholly unrestricted, allowing for max intake volume to feed the tuned engine.
Other than that, I can't recall anything further in my short visit with him. I Do prefer the look of the Aluminum intake, as it is closest to stock config.
One clever design feature he incorporated is the way he sealed the wiring for the side position lamp located on the exterior body. Instead of it going through the dead space of the snorkel, he's got a dedicated pipe running the loom through the area which effectively seals the intake from any ingress in that spot. Why Ineos' designers hadn't thought of that is beyond me.
As far as Knocks offroad, I imagine the aluminum unit will be plenty robust. It's all tig welded out of decently thick plates, then powdercoated.

I'd say it would have to take some serious blows before it showed signs of distress.
The stainless one is a bit more out of the way. Horses for Courses...
