High-Performance HEMI Air Box Solutions for 5.7L & 6.1L Engines

Engineered to maximize airflow and unlock your HEMI’s true potential

Optimized Air Intake Systems for HEMI Performance

Precision Parts Hub specializes in premium air intake solutions designed specifically for 5.7L and 6.1L HEMI engines. Our high-flow air boxes are engineered to deliver measurable performance gains while maintaining the durability and reliability your engine demands.

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 vs 6.1L HEMI Air Box Differences

While similar in design philosophy, our air intake systems are specifically tailored to each HEMI displacement:

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)

Technical Advantages of Precision Parts Hub HEMI Air Boxes

Our engineering team has developed several proprietary features that set our HEMI air intake systems apart from generic solutions:

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

Installation & Compatibility

Precision Parts Hub HEMI air boxes are designed for straightforward installation on a wide range of vehicles:

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:

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

Note: No ECU tuning required for basic installation

Performance Verification

Our HEMI air boxes deliver measurable improvements verified through:

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
