2004 + Subaru Impreza WRX/STI Turbo inlet hose

Delete the original inlet hose intact (it may be again)
1. do the factory service manual removal of intake manifold.
2. remove the original inlet hose.
3. Install PERRIN inlet hose.
4. in the reverse order, reinstall the intake manifold.
5. See instructions on the page (2) for the connection and the hose from inlet hose routing PERRIN.
Delete the original hose inlet in pieces (may not be again)
NOTE: THIS PROCEDURE ALLOWS YOU TO REMOVE THE FACTORY INLET HOSE WITHOUT REMOVING THE INTAKE MANIFOLD.
HOWEVER, THE HOSE FACTORY INLET IS DESTROYED IN THE PROCESS!
1. follow the factory service manual to remove doladowanego, intake, gastrointestinal-steering and throttle body.
2. Disconnect all snakes from the factory inlet hose and remove the foundations under the bolts joining hose to inlet manifold.
3. Cut and remove a crankcase ventilation (closest to the turbo inlet hose). 04 + cars will have a PVC on the diagnosis connector plugs. Simply disconnecting the sensor (s) and remove the protective plug from the inlet hose.
4. remove the bolt from the foundations control Purge solenoid. (For only temporary will be again)
5. unscrew the clamp on the turbo and carefully remove the factory inlet hose.
6. reinstall the purge solenoid control and tighten the screws.
7. Slip hose inlet under manifold PERRIN and the turbo. (NOTE: BENT WILL HELP SLIPPAGE AWL NEW HOSE OVER TURBO. DO NOT PUNCTURE THE HOSE WITH THE AWL!)
8. Install aluminium coupling to BOV returns connection at the inlet hose and tighten the clamp. Install the BOV return hose coupling aluminium and make sure that the installation of the OEM clamp.
9. reinstall the throttle in the reverse order of the authority, the line pressure assist steering, intake and intercooler. Note: Extruded in aluminium coupling in the large end of the inlet hose may be removed. This allows for a wide range of fitments with different intakes.
10. See instructions on the page (2) to connect the hose to the inlet hose routing and PERRIN

2004 + IMPREZA WRX/STI INSTRUCTIONS SUPPLIMENTAL
2004 and later WRX/STI's have additional plug-ins sensory connected to a duct intake. When the plug is connected to the factory tube an electrical connection is made, says ECU that PVC flexible hose is attached to the inlet. Hose inlet PERRIN requires skipping the connector. Again this is not "active" sensor. The connector terminates the circuit only. After the inlet hose is installed:
1. remove the grey PVC Diagnostics connector and hose leading to the crankcase ventilation. Crankcase vent is located on a block under the turbo. (see photograph)
2. inside the connector PVC diagnosis find pin jumper and remove it by using the needle nose pliers. This pin is lightly pressed into the electrical connector.
3. find the pipe/plug that was disconnected from the factory inlet hose and place pin jumper, which is removed form the grey connector PVC pipe to female pins/plug-ins. Electrical tape allows you to safely in place.
4. See instructions on the page (3) for the connection and the hose from inlet hose routing PERRIN.get
