Please read them BEFORE beginning the install to familiarize yourself with the steps and tools needed. If you feel you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician
IMPORTANT! Installing this kit will require custom tuning or utilizing an appropriate Stage Power Package map if you have a matching mechanical configuration. Please consult with COBB or an authorized ProTuner in your area.
While not necessary removing the intake manifold can make the installation easier in some ways particularly if you are doing the work at the same time you plan on installing fuel system upgrades. Removing the intake manifold streamlines the install of fuel injectors, rails and lines. For more information on how to do so check out our guide Subaru WRX & STI Intake Manifold Removal (EJ)
Inlet Hose Removal
Remove the EBCS line from the front port of the turbo inlet
Pop off the line going to the second port. The other end should go to the lower port of the canister purge solenoid.
Take off the larger hose behind that line that goes up into a blow-by sensor before attaching to the PCV crossover tube.
Locating the blow-by sensor towards the rear of the inlet, squeeze the release tab on the electrical connector while pulling outwards to remove the sensor from the inlet.
Using pliers remove the hose clamp holding the BPV recirculation tube on and take it off of the inlet.
Using a 7 or 8mm socket and extension remove the hose clamp holding the inlet onto the turbo.
Remove the 6mm hex head bolt on the front of the intake manifold holding the turbo inlet on.
Finagle the turbo inlet forward and out from under the manifold. If your inlet is already cracked or broken, breaking the inlet can make it much easier to get out.
