I had the inlet off mine recently to fit exhaust manifolds. The thought of doing it was far worse than the deed itself. Once you have the front bumper off and front cross member pulled forward its quite straight forward. A few pipe clips at the rear of the inlet manifold and two Allen bolts (one either side) and 10 6mm allen's along the front and lift it off. You'll have to remove the coil pack plugs and pull the wiring aside prior to that and a few other bits I'm sure. The part that gave me hassle was putting the front cross member back at the right position so that the panel gap between the headlights and wings were right.
Fairly straight forward just awkward. Toffs correct was me.
A long ball ended allen key for the bolt just above the alternator. Bumper, take that off. The drop forward the slam panel and rads. The rads then have to dropped out of their housin to allow u too see the manifold bolts.
I have some pics on the computer at home and can post up
Bit of new piping, just done my coolant caps, water cap etc, once I have a colour scheme to go for I will then spray manifold inlet, engine cover battery cover, and coolant cover once I purchase on that is
Ahhh, I think I do it the 'hard' way and just remove the front bumber.
Then undoing the crossmember bolts I use 2 large screwdrivers to keep the whole front end in place but allowing a few inches to come forward.
Using a mirror I fiddle and phaff trying to get all the manifold bolts out like this - seems like removing the front end out much more (like people say above) is quicker!
