Cold Air Intake for Nissan 350Z (2007-2008) 3.5L & 370Z (2009-2020) 3.7L Engine

Cold Air Intake System for Nissan 370Z / Infiniti G35 3.5L / 3.7L V6 (2007–2020) - Increased Output & Better Throttle

This cold air intake system is designed to replace the factory air box and intake tube on 2009–2020 Nissan 370Z models equipped with the 3.7L V6 engine and 2007–2008 Infiniti G35 models equipped with the 3.5L V6 engine. The system reduces intake restriction by using T304 aluminum piping and a high-flow air filter, allowing increased air volume to reach the engine. This results in improved throttle response, enhanced airflow efficiency, and measurable gains in horsepower and torque across the RPM range.

The intake uses larger diameter aluminum tubing compared to the factory intake tract, creating a less restrictive path for incoming air. The high-flow filter is engineered to provide adequate filtration while maintaining lower restriction than factory paper elements. The design maximizes airflow through the stock manifold system while maintaining compatibility with factory engine management components.

Vehicle Fitment

• 2009–2020 Nissan 370Z (3.7L V6 Engine)
• 2007–2008 Infiniti G35 (3.5L V6 Engine)

Performance & Design

Airflow Optimization: The system is engineered to improve airflow efficiency by eliminating restrictive elements in the factory air box assembly. The T304 aluminum piping provides a smoother, less restricted path for incoming air compared to the factory intake tube. Testing under controlled conditions has shown potential gains of up to 10% in horsepower and torque. Actual performance improvements will vary based on vehicle condition, elevation, ambient temperature, and existing modifications.

Throttle Response: The reduced intake restriction allows the engine to draw air more efficiently during acceleration. This results in improved throttle response and power delivery throughout the RPM range. The improved combustion efficiency may contribute to fuel economy gains during steady-state driving conditions.

Construction & Materials

T304 Aluminum Construction: The intake pipe is constructed from T304 lightweight aluminum, which provides corrosion resistance and reduces weight compared to factory components. The aluminum construction maintains structural integrity across engine bay temperature ranges while resisting oxidation and heat exposure.

Filter Design: The high-flow air filter is engineered for exceptional filtration while maintaining maximum airflow. The filter uses washable filter media that can be cleaned, re-oiled, and reused. The open-element design produces a more audible intake sound during acceleration, characteristic of the V6 engine configuration.

Features & Components

What's Included

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

Installation

• Direct replacement for factory air box and intake tube
• Uses existing factory mounting points
• No cutting or drilling required
• Installation time approximately 45–60 minutes
• Basic hand tools required (screwdrivers, socket wrenches)

Installation Note:
After installation, disconnect the negative battery terminal for approximately 30 seconds to allow the engine control unit to reset. This allows the ECU to recalibrate fuel delivery and ignition timing parameters to optimize performance with the modified airflow characteristics. Always disconnect the battery before performing any engine bay work. The ECU will continue to adapt during normal driving operation.

Filter Maintenance

Inspection Schedule: Inspect the air filter every 5,000 miles and clean if necessary. Driving conditions such as dusty environments, spirited driving, or heavy traffic 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 intake system is designed specifically for 2009–2020 Nissan 370Z models with the 3.7L V6 engine and 2007–2008 Infiniti G35 models with the 3.5L V6 engine. Verify your vehicle's engine and model year before purchase to ensure proper fitment.

This cold air intake system provides improved airflow characteristics for 3.5L and 3.7L V6 engines while maintaining reliable filtration through a washable, reusable filter element. The T304 aluminum construction provides durability and reduced weight compared to factory components. The system is designed to work with factory engine management components and stock manifold systems without requiring additional modifications or tuning.
