***REMOVING/INSTALLING INJECTORS: Please use your Factory Service Manual to supplement the
following steps.
1. Unplug the four factory injectors by squeezing the tab on the side of the plugs and pulling upwards.
2. Unbolt the 12mm nuts that hold the fuel rail to the head.
3. Remove the fuel rail from the cylinder head and set the fuel rail on the top of the valve cover.
4. Remove the four stock fuel injectors from the fuel rail. Be careful not to lose any of the o-rings
when removing them.
5. Remove the bottom o-rings from the stock injectors and install it on the new supplied injectors.
6. Slightly coat the outside of both o-rings with grease to ease installation of the injectors to the
cylinder head and the fuel rail.
7. Carefully insert the injector to the injector bungs on the head making sure the o-rings does not get
kinked. Make sure the injector plugs are facing toward the passenger side.
8. Re-install the factory fuel rail. Once the rail is on, tighten the bolts slightly with your fingers. Do
not tighten the rail to the head yet; slightly twist the injectors back and forth to make sure all the
injectors are seated properly.
9. Plug the injector harnesses to the injectors.
10. Tighten the nuts that hold the fuel rail to the cylinder head.
