2.7 Nitrous Spray Nozzle Installation
1. Determine nozzle mounting location in air inlet pipe, between air filter and throttle body, making sure the
nozzle, mounting collar, and the feed line from solenoid to
nozzle, do not interfere with any systems or components
of the vehicle.
2. Remove air inlet pipe.
3. Drill a 7/16” hole in inlet pipe where nozzle placement
has been determined.
4. Install nozzle mounting nut and collar onto inlet pipe.
5. Install inlet pipe.
6. Mark the spray direction on the nozzle.
7. Using liquid Teflon, install the spray nozzle into the air
inlet pipe making sure the nozzle discharge is toward the
vehicle’s engine.
8. Install recommended jet into nozzle fitting.
9. Install 3AN line from solenoid outlet fitting to spray nozzle jet fitting and tighten securely.
Here is a typical EFI solenoid/regulator assembly,
mounted in the engine compartment of an F-150
Lightning, using a non-modified EFI solenoid
bracket. Modifications performed to a solenoid
bracket depend on many factors. When mounting
the solenoid/regulator assembly on the vehicle,
considerations should be taken regarding any
potential interference with the vehicle’s systems or
components.
The line length between the Performer EFI
solenoid/regulator assembly and the jet fitting on
the nitrous spray nozzle is 12 inches. This should
also be considered when mounting the
solenoid/regulator assembly. We highly recommend
mounting the solenoid/regulator assembly in the
same location as on our F-150 Lightning for ease of
installation and access for servicing.
Shown to the left is a finished installation of the nitrous
spray nozzle and the solenoid/regulator assembly.
Notice the nozzle installation location in the intake boot.
The nozzle is mounted between two of the intake boot
ribs, with the nozzle outlet having a clean, unobstructed
spray route through the intake boot into the throttle
body. Make sure that the nozzle spray path sprays
directly towards the throttle body. Be sure that
when the 12 inch nitrous line is installed, it does not
interfere with any belts, pulleys, or other moving objects
to prevent serious damage to the nitrous system of
engine.
