Nitrous Express Billet Supercharger Lid

2015–2023 Dodge Demon, Challenger, Charger, Durango SRT Hellcat, Jeep Trackhawk & Ram TRX 6.2L HEMI

Part #: 20972BMF-15

Overview

The Nitrous Express Billet Supercharger Lid is a precision-engineered upgrade designed specifically for high-performance 6.2L HEMI engines found in Dodge Demon, Challenger, Charger, Durango SRT Hellcat, Jeep Trackhawk, and Ram TRX models from 2015 through 2023. This billet lid replaces the factory supercharger lid to deliver enhanced airflow and integrate nitrous oxide and water/methanol injection passages for significant horsepower and torque gains.

Ideal for enthusiasts seeking a clean, efficient, and powerful method to boost engine output, this lid features a spraybar-less nitrous system that injects nitrous and fuel directly into the supercharger’s air discharge. This innovative design ensures an even distribution of the nitrous/fuel mixture to each intake runner, improving combustion and maximizing power potential.

Key Features

The Nitrous Express Billet Supercharger Lid combines advanced engineering with practical performance enhancements. Key features include:

• CNC-machined billet aluminum construction for superior strength and durability
• Spraybar-less nitrous system with integrated nitrous and water/methanol passages
• Optimized airflow design to maximize supercharger efficiency and air charge volume
• Injection of nitrous and fuel inline with the supercharger air discharge for even distribution
• Pre-intercooler injection that super-cools the air charge, enhancing intercooler performance
• Direct replacement for factory supercharger lid with a straightforward installation process
• Compatible with 2015–2023 Dodge Demon, Challenger, Charger, Durango SRT Hellcat, Jeep Trackhawk, and Ram TRX 6.2L HEMI engines
• Improves horsepower and torque without compromising reliability or drivability

Construction & Design

Crafted from high-quality billet aluminum, this supercharger lid is precision CNC-machined to exacting tolerances. The billet construction not only provides exceptional strength and resistance to heat but also ensures a perfect fit and finish. The integrated nitrous and water/methanol passages are machined directly into the lid, eliminating the need for external spray bars and ensuring the nitrous/fuel mixture is delivered precisely where it is most effective.

The lid’s airflow design is optimized to complement the factory supercharger and intercooler system, promoting maximum volumetric efficiency and cooler intake temperatures. This results in improved combustion efficiency and increased power output while maintaining the reliability expected from OEM components.

Performance & Sound

By injecting nitrous oxide and water/methanol directly into the supercharger’s air discharge, this lid significantly enhances engine performance. The super-cooling effect on the intake charge reduces air temperatures, allowing for denser air and more efficient combustion. This translates into noticeable gains in horsepower and torque across the powerband without negatively impacting engine sound or drivability.

Installation & Fitment

The Nitrous Express Billet Supercharger Lid is designed as a direct bolt-on replacement for the factory supercharger lid on compatible 6.2L HEMI engines. Installation is straightforward and requires no permanent modifications to the supercharger or intake system. The integrated nitrous and water/methanol passages simplify plumbing and reduce installation complexity compared to traditional spraybar systems.

This product fits the following vehicles equipped with the 6.2L HEMI engine:

• 2015–2023 Dodge Demon
• 2015–2023 Dodge Challenger Hellcat
• 2015–2023 Dodge Charger Hellcat
• 2015–2023 Dodge Durango SRT Hellcat
• 2015–2023 Jeep Trackhawk
• 2015–2023 Ram TRX

What's Included

• Billet supercharger lid with integrated nitrous and water/methanol passages
