Product Details

The Nitrous Express NP616 is a high-performance crossbar pro-power plate designed for 4150-style carburetors. This nitrous plate system delivers adjustable power gains ranging from 100 to 500 horsepower, making it an ideal solution for street and strip applications requiring serious nitrous performance.

Key Features:

  • Compatible with 4150-style Holley carburetors and equivalents
  • Crossbar design ensures even nitrous and fuel distribution across all cylinders
  • Adjustable power range from 100HP to 500HP with proper jetting
  • CNC-machined aluminum construction for precise tolerances and durability
  • Pro-Power design maximizes flow efficiency for consistent performance
  • Installs between carburetor and intake manifold

This is the plate-only component, allowing you to upgrade or replace an existing plate in your Nitrous Express system or build a custom setup with separate solenoids and lines. The crossbar configuration provides superior nitrous distribution compared to single-point injection, resulting in more predictable power delivery and reduced risk of cylinder-to-cylinder variation.

Note: Requires separate nitrous and fuel solenoids, lines, jets, and bottle for complete installation. Proper tuning and jetting is essential for safe operation at desired horsepower levels.

Quick and easy ordering. Item was well packaged and in great condition.

Quick and easy. Great Prices.

Autoplicity was the cheapest place I could find for my Turbosmart Eboost2. I ordered my controller yesterday and they promptly gave me a receipt and a normal time frame for delivery. Today I got the tracking number and at lunch I got an email saying order complete and delivered. This was an awesome experience and I will definitely be using them next time i'm in the market for a similar product.

Ordered a thule fairing for an audi roof rack. The whole process was easy and shipping was fast. Best price too. Definitely will use them again.

I didn't get a shipping notice until three days after I got the product. It was exactly what I ordered and did arrive during the proper time frame

Purchased set of four Scribner 5 gallon utility jug. After doing considerable looking, Autoplicity had the lowest price by far in comparison to all other competitors. Communication has been great with items ordered shipped with tracking number the next day. Great buying experience.

Ok so far

Great prices and piece of cake ordering.

Easy payment and super fast shipping! Will order from again!

So far so good

Web interface seems a little clunky-----a lot of seemingly unnecessary scrolling.

Item arrived promptly (4 days after order), price was good and item was as described.
