Why Upgrade Your HEMI Air Box?

The factory air intake system on most HEMI engines is designed for quiet operation and cost efficiency, not maximum performance. Our aftermarket solutions address these limitations:

• Increased Airflow: Larger intake volumes and optimized pathways reduce restriction
• Improved Filtration: High-efficiency filters trap more contaminants while flowing better
• Cooler Air Intake: Strategic heat shielding pulls in denser, oxygen-rich air
• Enhanced Throttle Response: Immediate improvement in engine responsiveness
• HP Gains: Typical gains of 10-15 HP at the wheels (varies by application)

5.7L HEMI Air Box Features

• Precision-engineered for 2003-2024 5.7L applications
• Direct replacement for factory air box with no modification required
• Maintains all factory mounting points and connections
• Includes high-flow dry or oiled filter options

6.1L HEMI Air Box Features

• Designed for the higher airflow demands of the 6.1L engine
• Larger intake volume than 5.7L version
• Reinforced construction for high-performance applications
• Optimized for SRT models (Charger, Challenger, 300C)

Vortex Airflow Technology

The internal geometry of our air boxes creates a controlled vortex that:

• Increases air velocity entering the throttle body
• Promotes more even distribution across all cylinders
• Reduces turbulent airflow that can cause power loss

Thermal Barrier Construction

Our multi-layer construction combines:

• Rigid outer shell for durability
• Thermal insulation layer to reduce heat soak
• Smooth internal finish for optimal airflow

Vehicle Applications

• Dodge Ram 1500/2500/3500 (2003-2024)
• Charger/Challenger/300C (5.7L & 6.1L models)
• Jeep Grand Cherokee (HEMI-equipped models)
• Compatible with both stock and modified engines

Installation Process

Most installations can be completed in under 30 minutes with basic tools:

1. Remove factory air box assembly
2. Transfer any necessary sensors
3. Install new air box using provided hardware
4. Connect all hoses and electrical connections
5. Verify proper seating of air filter

Note: No ECU tuning required for basic installation

Dyno Testing Results

• Average gains of 11-14 HP at the wheels (5.7L applications)
• 13-17 HP gains on 6.1L applications
• Improved torque curve throughout RPM range

Real-World Benefits

• Noticeable improvement in throttle response
• Enhanced engine sound under acceleration
• Improved fuel efficiency in highway driving
• Longer service intervals than factory air boxes
