A. On the driver’s side, temporarily remove the

four screws that secure the coil-pack bracket

to the manifold and cylinder head. Unplug the

driver’s side plug wires where they connect at

the coil pack, to allow the coil-pack assembly

to be pulled back to access to the fuel rail

location. (See Fig. 5-a.)

B. Unplug the electrical connectors from each

fuel injector.

C. Remove the four bolts securing the injector

rails to the intake manifold.

D. Remove the small clips that retain the factory

fuel injectors to the fuel rail (if equipped).

Remove the factory fuel injectors and set

aside, these will not be reused.

E. Locate the supplied fuel injectors. Lubricate

the injector O-rings with clean motor oil and

install in to the fuel rail. Reinstall the small

retaining clips onto the injectors. (If equipped)

F. Lower the fuel rail/injector assembly on to the

manifold, making sure that the injectors seat

properly into the manifold.

G. The supplied fuel injectors are taller than the

factory injectors. Therefore, place the sup-

plied .45" spacers between the fuel rails and

the intake manifold and secure the fuel rails

using the four supplied M8-30mm bolts. (See

Fig. 5-b.)

H. Reconnect the fuel injector plugs.
I.

Re-install the driver’s side coil bracket and

reconnect the spark plug wires.
