Overview:

The Earl's Performance Billet Aluminum Gen III Hemi Supercharger Intercooler Manifold is engineered to address clearance and compatibility challenges commonly encountered with the factory intercooler manifold on supercharged Gen III Hemi engines. Designed specifically for high-performance vehicles such as the Dodge Challenger SRT Hellcat, Charger SRT Hellcat, Durango SRT Hellcat, Jeep Grand Cherokee Trackhawk, and Ram 1500, this manifold offers a more compact profile that facilitates engine swaps and custom installations.

By providing an additional 1.875 inches of clearance compared to the stock manifold, this component allows enthusiasts and professional builders to fit the supercharged Gen III Hemi engine into classic muscle cars, trucks, or other custom builds without compromising coolant routing or sensor functionality. Its compatibility with factory sensors and bleeders ensures seamless integration with existing engine management systems.

Key Features:

This billet aluminum intercooler manifold combines precision engineering with practical enhancements to improve fitment and durability. Key features include:

• Shortened design providing 1.875" additional clearance for easier engine swaps and tight engine bays
• Compatible with factory coolant sensor port (3/8” NPT female) and bleeder port (1/8” NPT female)
• Allows use of AN hoses for coolant lines, enhancing reliability and serviceability
• Constructed from high-quality billet aluminum for superior strength and heat dissipation
• Durable black anodized finish resists corrosion and adds a sleek appearance
• Precision CNC machining ensures perfect fit and finish for direct bolt-on installation
• Designed specifically for Gen III Hemi supercharged engines found in Hellcat and Trackhawk models

Construction & Design:

The manifold is crafted from premium billet aluminum, chosen for its excellent strength-to-weight ratio and thermal conductivity. This material helps dissipate heat effectively, maintaining optimal intercooler performance under demanding conditions. The black anodized finish not only protects the manifold from corrosion and wear but also provides a clean, professional look that complements the engine bay.

Its compact, shortened design is the result of careful engineering to reduce bulk without sacrificing coolant flow or sensor integration. The manifold’s ports are precisely machined to accept factory sensors and bleeders, ensuring no modifications are necessary for proper engine management and coolant system operation.

Installation & Fitment:

The Earl's Performance intercooler manifold is designed for direct replacement of the factory unit on supercharged Gen III Hemi engines. Installation is straightforward for experienced mechanics and enthusiasts familiar with Hellcat and Trackhawk platforms. The additional clearance provided by this manifold simplifies engine swaps into classic muscle cars or trucks where space constraints are common.

No special modifications are required to accommodate factory coolant sensors or bleeders, and the manifold supports the use of AN hoses for coolant lines, allowing for upgraded or custom coolant routing setups.

What's Included:

• Billet aluminum Gen III Hemi supercharger intercooler manifold with black anodized finish
• Factory sensor port (3/8” NPT female) and bleeder port (1/8” NPT female) pre-machined

Ideal For:

This intercooler manifold is ideal for performance enthusiasts, custom builders, and professional shops working on supercharged Gen III Hemi engines. It is especially beneficial for those performing engine swaps into classic muscle cars or trucks where clearance issues with the stock manifold are a concern. Additionally, it suits anyone looking to upgrade their cooling system with AN hose compatibility while maintaining factory sensor functionality.
