I've done this mod on my old Nisaan Terrano, and that was turbo charged. It does make a nice drone in the corner of the truck but not obtrusive at all. Remember the intake will be a scoop on the roof as on Subaru Impreza for example. The silicone pipe , although flexible, it's still pretty hard to bend and relatively smooth inside. The new route in is now nice and smooth compared to the stock Patrol intake box in the wing and then the twists and turns into the filter box. I'll be doing a pressure test when I finish it so I'll be able to give you guys an empirical answer to how much drag there is in the pipe compared to the stock intake
This is also legal in the UK and listed on my insurance modifications list.
Thanks for the back up by the way "mods" cheers. No offence taken by the way , I am welsh after all lol
