Product Details

The Nitrous Express Billet LT4 Supercharger Lid Nitrous System provides a complete direct-port style nitrous solution designed specifically for GM LT4 supercharged engines. This innovative system replaces the factory upper supercharger lid with a precision-machined billet aluminum component that integrates nitrous and fuel injection directly into each cylinder.

Key Features:

  • CNC-machined from solid billet aluminum for exceptional strength and durability
  • Direct bolt-on replacement for OEM LT4 supercharger upper lid
  • Internal nitrous and fuel distribution provides true direct-port performance
  • Single stage system with jetting for 100 to 300 wheel horsepower
  • Includes complete 12-pound nitrous bottle
  • 1/8 NPT ports machined into lid for easy water/methanol system integration
  • Clean, hidden installation with no external manifold or nozzles

This system eliminates the need for traditional direct port manifolds by injecting nitrous and fuel from within the supercharger itself, ensuring even distribution to all cylinders while maintaining a factory appearance. The billet construction provides a lifetime of reliable performance, and the integrated NPT ports allow for future upgrades including water/methanol injection systems.

THANK YOU IT WAS A GREAT SPIRINCE ORDER HERE

GREAT!!!!!

The ordering went very fast cant wait to see my new light bar on my truck, thank you autoplicity

Item was damaged in shipment. Contacted you via phone and was told they could do nothing and was instructed to submit an online inquiry. That was done. Was contacted 2 days later asking how to proceed with a return for refund or a replacement. I stated that now the item was in critical need for the time frame needed and asked if another one could be expedited at your expense (to be refunded you by the shipper FedEx), if that was the case I would choose to purchase another one ASAP and have it expedited and then would return the damaged one for a refund. Now it is the next day and still have heard nothing. Terrible customer service.

Great Job Guys! The customer service was very professional and I loved that they took paypal!<br><br>Thank you would recommend to a friend!

GREAT EXPERIENCE

Easy order placement, fast shipment
