Do you have a photo of what the box (with the pipe) looks like inside? Where did you need to modify the plastic in the engine bay for installation r3 intake?I haven't fitted it yet, as I need to sort out the battery relocation to make room. I should have all the bits to make a start soon.
Which coolant reservoir did you use? Do you have a photo? Fits ok with engine mount
I just went through a similar process and understand that some things need to be redone.
