Hey mate

Very straight forward job, don't need to remove the intake manifold or even the fuel rail.
Remove the flexible intake tube, then the funky black plenum looking thing. Held down with 2 bolts, 12mm heads with about 4 tubes running from them. Just disconnect them and remove the plenum from the car. Undo the hose clamps connecting the black tubes to the bottom of the throttle body. A small amount of coolant will leak out. Disconnect the tps and the other electrical connector. Remove the vacuum tube from the throttle body. Hold the throttle open and disconnect the throttle cable. I think the 4 screws holding the throttle body are 6mm Hex heads. Remove these and the throttle body will pull off depending on the age of the gasket. Now you have plenty of room to reach the injectors. On the fwd side of the fuel rail, underneath the fuel inlet tube is a bolt, 10mm head, remove this. The fuel rail itself is held on with 2 bolts, 12mm heads. The aft one is easy to access using a socket and a 12" extension. The fwd bolt is more of a pain due to being obstructed but some clever use with an open end spanner will remove this bolt. The fuel rail will now wobble about. Disconnect all injector electrical connectors as this will allow even more movement of the fuel rail and also help avoid unwanted breakages. At this point it's quite easy to remove each injector. When installing the new injectors, lube the orings and be very careful not to pinch these on installation. With all new injectors in place, line them up with the intake manifold and loosely install the 2 fuel rail bolts. Then check to make sure they are still aligned properly, then reconnect the electrical connectors, then torque the bolts up. If you torque them up first without connecting the electrical connector, you might find it in the wrong position and you want to avoid turning them as you risk tearing orings and seals. Everything else is basically a reversal of the removal. Don't forget the 10mm bolt holding the fuel intake tube to the manifold. When you first remove the injectors, you will get fuel spillage. Common sense applies, wear gloves and eye protection. Hopefully this covers everything. If not just ask.
