If they are just plug and play its pretty easy.
1.Pull the Auto-Shutdown relay in the fuse box under the hood. Crank the car up and let it die. Do it several times to vent the pressure in the fuel system.
2. Take of the injector cover.
3. Use a deepwell socket (13mm I think) to undo the studs that hold the fuel rail on (the same studs the cover pops onto).
4. Carefully pull the rail/injectors out of the motor. Have some shop towels ready as there will still be fuel in the rail, just not under pressure.
5. Pop off the injector clips with a flathead screw driver.
6. Pull the injectors off of the rail.
Reverse directions for install of the new ones. Don't forget to reinstall the injector clips when putting the new injectors on the rails. Also be careful to make sure the O-rings stay on the injectors, you don't want them to pop off and end up pushing them into the motor.
Hope this helps
