Ram Air Intake for Chevrolet Impala (2006-2008) 3.5L 3.9L V6 Engine - Red

Ram Air Intake System for Chevrolet Impala 3.5L / 3.9L V6 (2006–2008) - Direct Airflow & Better Throttle

This ram air intake system is designed to replace the factory air box on 2006–2008 Chevrolet Impala models equipped with 3.5L LZE or 3.9L LZ9 V6 engines. The system reduces intake restriction by eliminating the factory resonator box and corrugated intake tubing, using mandrel-bent T304 aluminum piping to create a direct air path to the throttle body. This results in improved throttle response, enhanced airflow efficiency, and measurable gains across the RPM range.

The intake uses smooth, mandrel-bent aluminum tubing to replace the factory plastic accordion-style intake tube. The design removes baffling and restrictive elements present in the stock intake system. Both the 3.5L LZE and 3.9L LZ9 engines share the same throttle body location and intake geometry, allowing this kit to provide proper fitment for both engine variants.

• Factory horsepower range: 211–242 HP

Performance & Design

Airflow Optimization: The system is engineered to improve airflow efficiency by eliminating the factory resonator box and corrugated intake tubing. The mandrel-bent aluminum piping maintains consistent internal diameter throughout each bend, reducing turbulence caused by the stock corrugated rubber hose. This allows the engine to reach peak torque earlier in the RPM range. Actual performance improvements will vary based on vehicle condition, elevation, ambient temperature, and existing modifications.

Throttle Response: The reduced intake restriction and direct air path allow the engine to draw air more efficiently during acceleration and passing maneuvers. This results in improved throttle response and power delivery throughout the RPM range, reducing the delayed response common with the factory intake system.

Construction & Materials

T304 Aluminum Construction: The intake tube is constructed from mandrel-bent T304 polished aluminum, which provides corrosion resistance and reduces weight compared to factory plastic components. The aluminum construction dissipates heat more efficiently than the factory resin components, helping to reduce intake air temperatures in the engine bay environment.

Filter Design: The high-flow air filter uses washable filter media that can be cleaned and reused. The filter provides adequate filtration while maintaining lower restriction than factory paper elements. The open-element design produces a more audible intake sound during acceleration, particularly under wide-open throttle conditions.

What's Included

• T304 polished aluminum intake pipe
• High-flow washable air filter
• Mounting hardware and clamps
• Installation components

Installation

• Direct replacement for factory air box and resonator system
• Direct bolt-on design
• No cutting or drilling required
• Installation time approximately 45–60 minutes
• Basic hand tools required (screwdrivers, socket wrenches)
• No tuning required

Installation Note:
Disconnect the negative battery terminal before beginning installation. After installation is complete, leave the battery disconnected for approximately 30 seconds to allow the engine control unit to reset and relearn the new airflow parameters. This allows the ECU to recalibrate fuel delivery and ignition timing to optimize performance with the modified intake system.

Filter Maintenance

Inspection Schedule: Inspect the air filter every 5,000 miles and clean if necessary. Driving conditions such as dusty environments, urban traffic, or performance driving may require more frequent inspection and cleaning.

Cleaning Procedure: Remove the filter from the intake tube. Gently tap the filter to remove loose debris. Apply an appropriate air filter cleaning solution to both the inside and outside of the filter element, working it into the filter media. Allow the cleaner to soak for approximately 10 minutes. Rinse the filter thoroughly with low-pressure water from the clean side out, continuing until water runs clear. Shake off excess water and allow the filter to air dry completely in a clean environment. Once fully dry, apply air filter oil evenly to the filter media according to product specifications. Allow the oil to wick through the filter material for approximately 20 minutes before reinstalling. Ensure the filter is completely dry before applying oil, as moisture will prevent proper oil absorption.

Compatibility Requirements

Engine Verification: This ram air intake system is designed for 2006–2008 Chevrolet Impala models equipped with 3.5L LZE or 3.9L LZ9 V6 engines across all trim levels including LS, LT, and LTZ. Both engine variants share the same throttle body location and intake geometry, ensuring proper fitment. Verify your vehicle's engine code before purchase.

This ram air intake system provides improved airflow characteristics for 3.5L and 3.9L V6 Impala engines by eliminating factory intake restrictions. The mandrel-bent T304 aluminum construction reduces turbulence and improves heat dissipation compared to factory plastic components. The system is designed to work with factory engine management components without requiring tuning or additional modifications.
