Product Details

The Nitrous Express 20421-15 Proton Plus Nitrous System with 15lb bottle delivers exceptional performance and reliability in a compact, easy-to-install package. This complete nitrous oxide injection system features a black anodized aluminum module housing high-quality, USA-made solenoids capable of delivering up to 150 horsepower to the wheels. The aluminum construction provides excellent heat dissipation, pulling heat away from the solenoids to ensure extreme durability under demanding conditions.

Complete System Includes:

  • 15-pound nitrous bottle
  • Six jet sets for 35HP, 50HP, 75HP, 100HP, 125HP, and 150HP power levels
  • Single Shark nozzle with adapter
  • Stainless braided nozzle lines
  • Extra-long braided stainless steel nitrous feed line
  • Stainless steel fuel line
  • Master arming switch for safe operation
  • Wide open throttle (WOT) activation switch
  • 40-amp relay with harness
  • Complete hardware and electrical connectors for installation

The Proton Plus system is designed for electronic fuel injected vehicles equipped with a single throttle body, making it an ideal upgrade for a wide range of applications. The included jetting options allow you to tune power output from mild 35HP gains to aggressive 150HP shots, giving you complete control over performance levels. The compact module design simplifies mounting and installation while maintaining a clean, professional appearance in your engine bay.

Fast shipping times! Great prices!

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.

Had the best pricing for the item I wanted and customer service was excellent. Called about shipping and were responsive and quick to get me the details. Will buy from them again.

Definitely the lowest price! Quick shipping, and great communication and follow-through.

Easy ordering

Excellent and very quick service. I could not find this product in stock from any other supplier so I kept hunting. I found Autoplicity and from now on they are the first company I will try. Thank you.
