The Nitrous Outlet Inner Plenum Direct Port System provides adjustable horse power levels from 100 to 1000 HP and is designed to install into most intake manifolds with a large open plenum. The unique design of the Inner Plenum Direct Port provides the most precise cylinder to cylinder distribution possible. The Nitrous and Fuel enter through the front and rear passage of the plenum bar, filling the inner channel, feeding each plenum nozzle and discharging directly into each intake runner. The nitrous and fuel jets are located at each plenum nozzle, providing the capability to adjust the amount of nitrous and fuel volume into each individual cylinder.

Not only does the Inner Plenum system provide a really clean installation, but is a perfect option for the racer that has multiple stages and is space limited.

How does the Inner Plenum Direct Port System compare to a traditional Direct Port System or Plate System?

• Direct Port:

The Inner Plenum Direct Port System is similar to a direct-port application in the sense that it is discharging directly into each individual intake runner, allowing the ability to adjust nitrous and fuel volume per intake runner like you would with a traditional direct-port application, however it is mounted inside the intake manifold which makes jet changes more labor intensive.

• Nitrous Plates:

The Inner Plenum Direct Port System uses a completely different technology than the Nitrous Plates, which are designed to bolt between the throttle body / carburetor and intake manifold. Nitrous Plates are designed to saturate the intake plenums incoming air flow, allowing the engine to pull the atomized mixture into each intake runner and do not have the ability to adjust nitrous and fuel volume per intake runner like you would with an Inner Plenum Direct Port application.

Construction:

The Nitrous outlet Inner Plenum Direct Port System is custom built to each intake manifolds unique requirements. The Inner Plenum Direct Port is designed to work in most intake manifolds with a large open plenum. The installation of the Inner Plenum Direct Port System requires sending the intake manifold to Nitrous Outlet. Nitrous Outlet machines the intake and components, then installs them making sure that the discharge ports perfectly align with each intake runner.

How do I get an Inner Plenum Direct Port System?

Orders for the Nitrous Outlet Inner Plenum Direct Port System are similar to our blower spray bar, puck and direct port installation process. You will need to contact a Nitrous Outlet sales representative. The sales rep will work one on one with you to build a quote based upon your exact needs and intake manifold design. Once you approve the quote the sales rep will need some info from you to fill out a fabrication sheet, then provide you with a fabrication order number to write on the box when your intake manifold ships to Nitrous Outlet. Once your intake arrives to Nitrous Outlet the sales rep will contact you to let you know it arrived safely and to go over any final details. When the fabrication department and intake specialist are finished building your system the sales rep will contact you to finalize your order for shipment back to you.
