Product Details

The Nitrous Express NP302 is a high-performance nitrous plate designed for 4150-style carburetors with 2-barrel applications. This Stage 6 plate offers progressive power capabilities from 50 to 300 horsepower in 50hp increments (50-100-150-200-250-300hp), giving you complete control over your nitrous delivery.

Advanced Design Features:

  • Direct-port injection design with no spray bars that can sag, split, or break over time
  • Superior nitrous and fuel distribution for consistent power delivery
  • Exceptional atomization technology ensures complete mixture for safe, reliable operation
  • Precision-machined aluminum construction for durability and proper sealing
  • Fits between carburetor and intake manifold for easy installation
  • Next-generation plate technology proven on the track and street

This is the plate assembly only and requires separate nitrous and fuel solenoids, lines, and bottle system. The NP302 represents Nitrous Express's commitment to performance and reliability, eliminating common failure points found in older spray bar designs while delivering maximum power gains safely.

They had great email communication and shipped my items from order number 14199 very quickly. I was very impressed with how they handled my order.

Damn fast on the shipping and great price on the item a great place to shop

Great company to order from! Low prices, wide variety of merchandise, and quick shipping!

fast and easy

I was looking for a present for my husband, and Autoplicity had the items way cheaper than any other site. And then I messaged them to see if they had any coupons available, and I was sent a coupon code right away. I will definitely shop here again for auto supplies.

best price i can find. shipping scheduled only 4days after i order. haven't received it but looks fast.

Great prices, quick ship thanks!

very fast

This was my second order with Autoplicity. The first order I had to call to get an update, but just happens the part was out for delivery the day I had called. This second order went without a hitch! In both cases, shipping was fast and the products delivered at great prices, not to mention some of the best prices on shipping. I will definitely look here for my future parts needs!!

i was advised by all internet sources, and the manufacturer that the part i needed was out-of-stock and discontinued, when i used google shopping, autoplicity not only had the part but they were the most reasonably priced! my order was delivered to my door in 3 days. color me a satisfied customer, and yes i will used autoplicity again, soon!
