Product Details

The Nitrous Express NP606 is a high-performance nitrous oxide injection plate designed for 4150-style carbureted applications. This Stage Six crossbar plate delivers progressive power increases from 50 to 300 horsepower in 50 HP increments (50-100-150-200-250-300 HP), making it ideal for racers and performance enthusiasts who demand precise nitrous control and maximum versatility.

Key Features:

  • Progressive six-stage design allows tuning from 50 HP up to 300 HP
  • Precision-machined aluminum construction for durability and optimal flow
  • Crossbar plate configuration ensures even nitrous and fuel distribution
  • Direct fit for 4150-style carburetors (Holley and compatible)
  • CNC-machined with integrated distribution bars for consistent performance
  • Plate-only design for custom system builds or upgrades

This nitrous plate installs between the carburetor and intake manifold, providing a complete nitrous and fuel distribution solution. The staged design allows you to dial in the exact power level needed for your application, from street performance to all-out racing. Note that this is the plate only and requires additional nitrous system components including solenoids, lines, bottles, and jets to complete the installation.

Exactly what I needed & delivered in a timely manner....very satisfied

easy to order

Good

Ok

Hi mom!

The only feedback I have for improvement is just that pictures on the website didn't match the description. Like way off. For example it showed a brake caliper when the description was for a radiator hose. Now I get it, with hundred of thousands of parts it's probably not feasible or necessary to have photos of everything but I found the obvious disparate photos very distracting. In those cases just use a 'no photo' symbol or something like that. Overall I'm very, very happy with price, availability, selections, etc. I will definitely be shopping again!!!!

Great experience

Great experience!

Super seller

So far great.

very good deal.

easy to use

Smooth transaction.

Happy with interface, we'll see if it arrives and is what I ordered.

So far, so good.

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

Quick,easy,just the way every company should be. Thank you!

The Westin T-Max winch cover seems to be of good quality and it fit my off brand winch. It would be nice if it came with the bindings though. Good product.
