Nitrous Express Billet Supercharger Lid Nitrous Kit

Fits Most Dodge/Jeep 6.2L (15-21)

Part #: 20972-00

Overview

The Nitrous Express Billet Supercharger Lid Nitrous Kit is a precision-engineered upgrade designed specifically for Dodge 6.2L HEMI Hellcat and Demon models from 2015 through 2023. This billet aluminum supercharger lid replaces the factory component to deliver a seamless installation and enhanced performance. By integrating nitrous oxide and water/methanol injection passages directly into the lid, this kit provides a clean, spraybar-less nitrous delivery system that maximizes horsepower and torque gains without compromising reliability.

Ideal for enthusiasts seeking a straightforward yet effective power boost, this kit leverages improved airflow dynamics and innovative nitrous injection placement to super-cool the intake charge. The result is increased air density and optimized intercooler efficiency, translating to significant performance improvements on street or strip.

Key Features

This billet supercharger lid nitrous kit incorporates advanced design elements to ensure consistent, high-performance results:

• Direct replacement for factory supercharger lid on 2015–2023 Dodge 6.2L HEMI Hellcat and Demon platforms
• Spraybar-less nitrous system with CNC-machined nitrous and fuel passages integrated into the lid
• Optimized airflow design for maximum air volume and minimal restriction
• Injection of nitrous and fuel inline with the supercharger air discharge for even distribution to each cylinder runner
• Pre-intercooler nitrous injection that super-cools the intake charge, enhancing intercooler efficiency
• Durable billet aluminum construction for strength and heat resistance
• Clean, no-drill installation that replaces the factory lid without modifications
• Compatible with water/methanol injection systems for additional charge cooling and detonation control
• Designed to support horsepower increases in the 100 to 300 hp range

Construction & Design

Crafted from high-quality billet aluminum, this supercharger lid offers superior strength and thermal stability compared to the factory plastic lid. The precision CNC machining process ensures exact fitment and flawless integration of nitrous and fuel passages. The spraybar-less design eliminates the need for external spraybars, reducing potential leak points and simplifying the system layout. The lid’s internal channels are engineered to deliver a perfectly balanced nitrous/fuel mixture directly into the supercharger’s air discharge, promoting uniform distribution and efficient combustion.

Performance & Sound

By injecting nitrous oxide and fuel into the pre-intercooled hot air discharge, this system super-cools the intake charge, increasing air density and volumetric efficiency. This results in notable horsepower and torque gains without sacrificing drivability. The billet lid’s design also helps maintain the factory intercooler’s effectiveness, ensuring consistent performance under demanding conditions. While the nitrous system primarily enhances power output, it does so without altering the vehicle’s exhaust note or introducing unwanted noise.

Installation & Fitment

The Nitrous Express Billet Supercharger Lid is a direct bolt-on replacement for the factory supercharger lid on all 2015–2023 Dodge Hellcat, Demon, Challenger, Charger, Durango SRT, Trackhawk, and TRX models equipped with the 6.2L HEMI engine. Installation is straightforward and requires no modifications or drilling. The integrated nitrous and fuel passages simplify plumbing and reduce installation time compared to traditional spraybar systems. This kit is designed for use with Nitrous Express nitrous and water/methanol injection components to ensure optimal compatibility and performance.
