Product Details

The Nitrous Express NP954 is a high-performance dual-stage nitrous plate system designed for 4150-style 4-barrel carburetors. This professional-grade nitrous plate delivers progressive power in two stages, with the first stage providing 50-300 horsepower and the second stage adding an additional 100-500 horsepower for a combined total of up to 800 horsepower.

Key Features:

  • Dual-stage nitrous injection for progressive power delivery
  • Fits standard 4150 flange 4-barrel carburetors (Holley, Quick Fuel, etc.)
  • First stage: 50-300 HP boost range
  • Second stage: 100-500 HP boost range
  • Precision-machined aluminum construction for optimal flow
  • Direct bolt-on installation between carburetor and intake manifold
  • Pro-Power design ensures even nitrous and fuel distribution

This plate-only system allows experienced nitrous users to build a custom dual-stage setup or upgrade an existing single-stage system. The Pro-Power plate features strategically positioned spray bars that deliver a uniform nitrous and fuel mixture to all cylinders, ensuring safe and consistent power gains. Requires separate nitrous solenoids, fuel solenoids, jets, lines, and bottle for complete installation.

I own a 25' travel trailer without side trining signals. This light was exactly what I needed for additional safety feature of notifying vehicles of my intended movement.

Had just what I wanted

Excellent Service.

PICTURE ON WEB PAGE IS VERY CONFUSING TO WHAT I WANTED TO ORDER- AFTER RECEIVING ITEM, NOT WHAT I NEEDED. THE REP ON THE PHONE WAS HELPFUL TO FIND CORRECT ITEM I WILL BE PLACING ORDER FOR THAT ITEM( WHICH I WOULD NOT HAVE THOUGHT WAS CORRECT BY PICTURE ON WEBSITE). I AM WAITING FOR A RETURN VERIFICATION (I SUBMITTED FOR A RETURN) MIKE

Great purchasing experience!

good deal fast shipping thank you

Autoplicity had the lowest price by far and shipping was very fast (ordered Wednesday evening, arrived Saturday morning). I will definitely order from Autoplicity again!

good

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.
