Well it is done. I will write it up with pictures later, but it's not too hard. The main concerns are making sure you can remove the 4 pipes from the plenum without damaging of breaking the retaining clips.
I currently have an erratic idle which I'm hoping by giving it a run out today will solve it.
Thanks for all your help and input guys. I did what you said Ming, lightly did all the bolts then nipped them up. I have a torque wrench, but it's lowest setting is 30 lb ft, so I didin't use it on this. The Kinetix instructions show even lower figures as it isn't as sturdy as the OEM one.
Pictures to follow......
Edit - pics here - not great quality as taken by a muppet, in the dark, in a rush!
They don't do it justice at the moment. Will get some done in better conditions.
