I found it pretty straightforward, the things that caught me out were looms cable tied to the bottom of the old manifold that I never noticed... and don't drop the bolts when you're putting the new manifold on, that's a real nuisance :wink:
I found it easier to unclip the injectors as it allowed a bit more play in the looms when moving the manifolds about. Didn't need to remove the dipstick tube, though.
Well worth a look at the fitting guides, as all the information is there, even if it's not identical.
