Nitrous Express Billet Supercharger Lid w/ Integrated Nitrous Passages (Lid Only) for Dodge Hellcat / Demon Platforms
The Nitrous Express Billet Supercharger Lid is engineered for the 2015–2021 Dodge Challenger SRT Hellcat, 2018–2021 Challenger Demon and various Charger Hellcat applications. This direct-replacement lid is machined from a solid chunk of billet aluminum, delivering improved airflow, more pronounced supercharger whine and built-in nitrous/fuel distribution passages for optimum performance in nitrous-equipped forced-induction engines. Key Features
- Billet Aluminum Construction: CNC-machined from a solid block for strength, precision fitment and performance upgrade.
- Integrated Nitrous & Fuel Passages (Spraybar-less Design): Allows nitrous/fuel mixture to be evenly distributed directly into the supercharger rotor discharge without a traditional spray bar.
- Improved Airflow & Whine Enhancement: The design increases airflow by itself (even without nitrous), enhancing the blower sound and performance.
- Direct Fit for Hellcat/Demon Platforms: Designed specifically for 6.2L HEMI Hellcat/Redeye/Demon/Charger Hellcat applications for years 2015–2021.
Product Notes
- This listing is for the **Lid Only** version additional nitrous system components (lines, solenoids, jets, trunk‐mounted bottle, etc.) are **not included**.
- Because this is a high-performance component designed for nitrous-system integration, professional installation is strongly recommended to ensure proper sealing, alignment and nitrous/fuel system tuning.
- Modifications involving nitrous or altered induction may not be legal for street use in all jurisdictions, check state and federal laws. For example, one listing notes this product is “not CARB legal” in California.
Installation Notes
- Remove the factory supercharger lid and use the OEM mounting points for the replacement verify sealing surface and alignment.
- Ensure the supercharger rotors and discharge ports are correctly aligned and that gaskets/seals are properly installed to avoid leakage or boost loss.
- If using the integrated nitrous/fuel passages, ensure all system components (fuel system, nitrous bottle, solenoids, plumbing, engine management, etc.) are properly configured to match the upgraded lid’s distribution design.
