Product Details

The Nitrous Express 63071-12 Covert Crossbar Plate System delivers professional-grade nitrous injection for 4500 series carburetors with incredible power flexibility from 50 to 300 horsepower. This Stage 6 system features a unique crossbar plate design that fits beneath your carburetor, providing superior nitrous and fuel distribution while maintaining a sleek, hidden appearance that keeps your setup looking completely stock.

Key Features:

  • Stage 6 configuration with 50-300 horsepower range for maximum tuning flexibility
  • Covert crossbar plate design mounts under carburetor for concealed installation
  • Precision-machined aluminum construction for optimal flow characteristics
  • Includes 12-pound nitrous bottle for extended run capacity
  • Compatible with 4500 series carburetors (Dominator flange)
  • Complete system with all necessary jets, lines, and hardware
  • Engineered spray bars ensure even distribution across all cylinders
  • Adjustable power levels via jet changes for different racing conditions

This complete nitrous system is ideal for racers and performance enthusiasts who want serious power gains without the obvious appearance of a traditional plate system. The crossbar design provides excellent atomization and distribution while fitting in tight engine bay configurations. Perfect for street/strip applications where you need big power on demand with a clean, stealthy look under the hood.

Was quick easy and painless, Thanks

So I was skeptical due to a lot of negative reviews online, but I seen they had a great price for Toyo extensa II tires about half the price of everywhere else. So I bought all 4 with the free shipping option, and they were shipped to me in 3-4 days each tire had a different tracking number but they all showed up at the same time. So I will definitely use the site again.

Very cheap very quick

Excellent service! Fast shipping and a great price. I couldn't be happier!
