A1. 1998-2000 - EGR removal, relocation/heat
shield installation
1. Remove EGR valve. Using thread sealer, in-
stall 1/8" NPT plugs in the EGR relocation
plate.
2. Using the new supplied gasket, bolt the EGR
valve to the relocation plate using 5/16” bolts
and washers.
3. Install EGR relocation plate and heat shield
using new gasket and supplied 8mm bolts.
The heat shield should be oriented so that the
aftercooler core can rest on top of it when in-
stalled (see
Fig. 10-a).
4. Place supplied 1/4" foam tape on top of the
heat shield (see Fig. 10-a).
5. Using the supplied wire and butt connectors,
lengthen the EGR plug wire approximately
10”. Stagger butt connectors and wrap with
electrical tape. Connect the lengthened EGR
plug to the EGR valve using a wire loom and
zip ties to keep it away from hot or moving
parts.
A2. 2001-2002 - Charge air cooler support installation
1. Install the supplied support bracket onto the
front of the passenger side cylinder head. Use
the supplied M10 bolts to secure the bracket
with the bent portion on top and pointed for-
ward. (See
Fig. 10-b.)
2. Verify that the 1/4" foam tape is on top of the
bracket to insulate the aftercooler from metal
to metal contact.
B. Air conditioning canister relocation
1. Loosen the clamp on the factory A/C canister
bracket. Adjust the height of the A/C canister
so the supplied #56 hose clamp fits between
the top of the factory A/C canister bracket
and the raised step on the A/C canister.
2a. Vehicles With Traction/Cruise Control. Locate
the traction/cruise control servo on the
passenger's side just behind the battery. Re-
move the bolt closest to the A/C canister which
secures the servo to the strut tower. (It may
be beneficial to remove the battery to gain full
access to this bolt.) Insert the supplied A/C
canister anchor between the cruise control
servo and the strut tower. Install previously
removed bolt, hand tight only.
2b. Vehicles Without Traction/Cruise Control.
Mount the A/C canister anchor in the factory
hole near the middle of the A/C canister. Us-
ing one of the original EGR valve mounting
bolts removed in Step 10-a or use the sup-
plied 8mm bolt and washer and tap the hole
to M8 x 1.25. (See
Fig. 10-2b.)
NOTE: EGR valve inlet passage must remain
connected to the same passage as
factory installed. (i.e.: pointed side
of EGR valve mounting surface must
point towards the center of the
vehicle).

10. CHARGE AIR COOLER ASSEMBLY INSTALLATION, (for non-charge air cooled
standard supercharger kit installation, go to step 11)
NOTE: The object of this section is to pull the
A/C canister towards the passenger
side of the vehicle to provide clearance
for the charge air cooler.
