Installation Instructions for GFB Respons T9003
Applicable vehicles:
•
WRX MY01-07
•
STi MY02-on
•
Forester XT MY05-08
NOTE: the flange on the Respons may appear to be loose, but this is normal and does not
affect its ability to seal properly – once installed the valve will be clamped firmly.
On Impreza models without an electronic throttle, it is necessary to move the intercooler to gain
access to the hose clamp under the factory valve. It does not need to be removed completely; it just
needs to slide back far enough to reach under. These instructions take you through it step-by-step.
For Impreza models with an electronic throttle and also Forester XT models, it is usually possible to
access the clamp without shifting the intercooler. In this case, simply ignore the steps 1, 3, 4 & 5.
1) Pull off the hoses from aluminium
tubes that run across the front of the
intercooler (2 on the left and 1 on the
right hand side. See figure 1, step 1).
2)
Using a 12mm socket or wrench, undo
the bolts that hold the factory blow-off
valve and remove, leaving it supported
by the hose. Take care not to drop the
bolts or gasket from behind the valve
(figure 1, step 2).
3)
On the hose between the intercooler
and throttle body, loosen the hose
clamp closest to the intercooler, and the
clamp holding the hose onto the outlet
of the turbo (figure 1, step 3)
Figure 1
4)
Undo and remove the two mounting bolts (again
with the 12mm socket or wrench) that hold the
intercooler in place (figure 1, step 4).
5)
Carefully slide the intercooler back just enough
to access the hose clamp on the BOV (figure 2).
Take care when handling the intercooler since
the cooling fins are very fragile, and also take
care not to bend the hose from the turbo too
much.
6)
Take note of the position of factory valve and
then use pliers to open the recirculation hose
clamp (figure 2). Remove the valve from the
recirculation and vacuum hoses.
