1.1 General Information
The Edelbrock Performer EFI Nitrous System (Part Number 70406) is designed for the 2003 & Later Mercury
Marauder with stock or slightly modified 4.6L DOHC engines. Horsepower and torque increases can vary with
equipment upgrades and modifications.
This system utilizes two nozzle. One is installed in the intake box just before the Mass Air Flow sensor (MAF) and one before
the throttle body. The additional fuel needed is supplied by the vehicle’s standard fuel system.
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.
Call 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.
