Product Details

The Nitrous Express NX346 is a complete plate conversion kit designed specifically for Ford 4.6L 2-valve Mustang engines, allowing you to upgrade from a single nozzle wet nitrous system to a high-performance plate system. This kit delivers 50-150 wheel horsepower gains with superior nitrous and fuel distribution compared to traditional nozzle-based systems.

Next Generation Plate Technology:

Nitrous Express plates feature advanced design with no spray bars that can sag, split, or break over time. The plate design provides exceptional atomization of the nitrous and fuel mixture, ensuring even distribution across all cylinders for maximum performance and engine safety. This superior distribution helps prevent cylinder-to-cylinder variation and reduces the risk of detonation or lean conditions.

Complete Conversion Kit Includes:

  • Nitrous injection plate engineered for 4.6L 2-valve applications
  • Mounting gasket for proper sealing
  • 5 mounting bolts for secure installation
  • Support spacer for structural integrity
  • 24-inch stainless braided nitrous hose with 16109 fitting
  • Jetting for 50-150 horsepower range

Performance Benefits:

  • Upgraded wet system delivers both nitrous and fuel through the plate
  • Superior atomization ensures consistent air/fuel ratios
  • Even distribution across all cylinders maximizes power and safety
  • Durable construction with no internal spray bars to fail
  • Adjustable power levels from 50-150 wheel horsepower with jet changes

This conversion kit is ideal for Mustang owners looking to upgrade their existing single-nozzle wet system to a more advanced plate system that offers better distribution, easier tuning, and more reliable performance. The plate installs between the throttle body and intake manifold, providing a clean and effective nitrous delivery solution.

awesome

Best Price I could find, fast shipping. I shall return!

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Great price

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Fast shipping. And great cust service.
