The heart of this
power-adding
system, designed
specifically for the
Jeep 3.6L V-6 in
the 2018-and-up
Jeep JL Wrangler,
is the P-1SC-1
ProCharger super-
charger. Running
7 psi of boost, the
blower features
a self-contained
oiling design (no
external oil lines
required) and
is designed to
operate in extreme
temperatures,
making it ideal
for the Jeep
enthusiast.
There are nine basic groups of steps to this
installation. The first begins with the discon-
nection, disassembly, loosening, or removal
of the battery, engine cover, air inlet tube,
airbox, air pump on the alternator bracket,
pulley belt, alternator, radiator, and grille. We
went one step further and pulled the electric
fan and shroud assembly on the back of the
radiator for more elbow room when working.
The first move in the second group of steps
is what we called “spark and fuel,” because
the removal of the upper intake manifold and
throttle body as a single piece must be done
to replace the spark plugs and injectors with
new and upgraded replacements from the
ProCharger kit.
This is where the right tools really
come in handy. The spark plugs
you need to replace are deep
down under the coils. A magnetic
plug socket on a long exten-
sion was used to pull the factory
plugs and replace them with the
NGK 1422 plugs that came as an
option with our kit. If getting your
own plugs, ProCharger recom-
mends one heat range colder
than the stock plugs, gapped at
0.035 inch. A drop of antiseize on
the new plug threads was applied
just prior to installation.After unplugging all the injector and coil
connectors, we pulled the factory coils so we
could get down into the tubes and pull out
those factory spark plugs.So that nothing stupid (you know, like a screw
falling down into the engine through the open
ports of the lower intake manifold) happened,
we immediately covered the ports with strips
of painter’s tape.The T- 30 Tor x fuel r ail screws were removed
so the fuel rails could be pulled loose. It’s
a good idea to have r ags ready to soak up
spilled fuel during this operation.The fuel rails were reinstalled with the same
T-30 Torx screws that came out of them, the
injector connectors were hooked back up, and
then the coil connectors were refastened and
the hold-down screws were reinstalled. Now
the upper intake and throttle-body assembly
can be reinstalled just as it came out.We unplugged the injectors, flipped the fuel
rails over, and replaced the factory injec-
tors. The new fuel injectors included with the
ProCharger kit are rated at 50 lb/hr, which is
a serious upgrade from the factory injectors.
A small amount of grease was applied to the
O-rings on the new injectors before installation.
