Product Details

The Nitrous Express NX618 is a high-performance billet crossbar nitrous plate conversion system designed for Dominator 4500 flange applications. This Pro Power conversion kit is engineered for serious performance enthusiasts seeking 100-500 horsepower gains with superior nitrous distribution and spray pattern control.

Advanced Crossbar Technology:

  • CNC-machined billet aluminum construction eliminates traditional round spray bars for improved atomization and cylinder distribution
  • Crossbar design prevents spray bars from sagging, rotating, or disrupting airflow
  • Engineered specifically for Dominator 4500 flange intake manifolds
  • Compatible with carbureted applications requiring high-flow nitrous delivery

Complete Conversion Kit Includes:

  • Custom solenoid mounting bracket for clean installation
  • Billet aluminum Y-fittings for efficient nitrous and fuel distribution
  • Braided stainless steel lines from solenoids to plate
  • Nickel-plated fittings for corrosion resistance
  • Extended carburetor mounting studs
  • Jetting options for precise tuning across 100-500 HP range

This conversion system provides the performance advantages of a billet crossbar plate design while integrating seamlessly with your existing Dominator-flanged intake setup. The Pro Power designation indicates this kit includes premium components and comprehensive hardware for professional-grade installations.

Small holdup with shipping, however the great customer service team promptly corrected the issue and the item was received 3 days after. Product was exactly as described. Great company, great prices, great customer service. Will definitly do business with in the future.

Great

Great site, Thanks

Found the item via Amazon, at a lower price than Amazom, and Paid via my Amazon account. Quick, easy, and less expensive. I shall return!

So far so good

Great pricing ! Items in stock !! Thank you

Fast check out. Good price.

Like other customer reviews, so i hope service is consistent.

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

Great!

Cheapest price, manufacturer direct

Good price for high quality product. Very fast delivery too!

Price is awesome

Autoplicity offered the best internet price, and utilized Paypal for guaranteed customer service. Shipping tracking through UPS is accurate and customer focused. I'm very pleased with the retail experience, and will use Autoplicity on future orders and best prices.
