1.1 General Information
The Edelbrock 2002-2004 Subaru WRX Nitrous System (Part Number 71003) is designed for
installation on any WRX within this year break. Horsepower and torque increases can vary with equipment
upgrades and modifications.
The system utilizes one “wet” style nozzle that is installed in the intake boot just after the intercooler and before
the throttle body. This nozzle delivers the precise amount of nitrous and additional fuel needed to make a safe, but
substantial horsepower gain.
This system has been designed with some flexibility as to where certain components can be located to allow easy
installation on vehicles with upgraded or modified equipment . The solenoid and microswitch brackets are designed
to be manipulated (bent, cut, twisted, etc.) and the electrical components have properly sized and ample lengths of
wire.
This system includes the bottle (shipped empty), bottle feed line and universal footprint steel bottle brackets. The
mounting brackets also include rubber insulators to protect the surface of your nitrous bottle while mounted in the
brackets. When installing your nitrous bottle, pay close attention to the installation instructions for the location of
your bottle. Make sure that the installation of your bottle does not interfere with any systems that may lie under
the location where you plan to drill holes for mounting the brackets.
Contact your local automotive store, motorcycle shop or race track for refilling of your bottle. Trust a professional
to properly fill your bottle and reference your installation manual when re-installing your filled bottle back into your
vehicle.
Always take care when handling a full bottle of nitrous oxide. Please reference this manual for further safety
measures to take during the handling of a nitrous oxide bottle.
Please follow all safety methods during the installation of your Edelbrock Nitrous System, and follow all vehicle
regulations and road laws when using your nitrous system.
