1. Install the bottle nut adapter (1) and Teflon washer (2) on the nitrous bottle (3). Tighten securely.
2. Loosely install the bottle mounting brackets (4 & 5) on the nitrous bottle, as shown in Figure 3E.
3. Locate the bottle/bracket assembly in the desired mounting location, ensuring that the location will provide easy access to
the bottle valve, hose connection, and bracket clamp bolts to facilitate bottle changing.
4. Use the assembled bottle/bracket unit as a pattern to mark and drill four 5/16” holes in the mounting surface.
CAUTION! When drilling or punching holes for these brackets, be aware what component, wires, or hoses are located
or routed behind the general area to avoid vehicle or equipment malfunction.
5. Mount the brackets securely to the surface (recommended minimum of 5/16” bolts or No. 12 sheet metal screws).
6. Secure the nitrous bottle in the mounting brackets and tighten the bracket clamps.
2.4 Soft Plume Nozzle Installation
NOTE: The recommended mounting location for the Soft Plume nozzle is in the air inlet duct, between the throttle body and the
mass airflow sensor (in applications where a mass airflow sensor is used). Install the nozzle (as shown in Figure 5)
before the throttle body or any major turn in the air inlet duct. See Figure 5.
1. Before making any permanent modifications to the vehicle, layout the location of all the major components (solenoid,
nozzle, fuel/nitrous supply lines, etc.).
