Cold Air Intake System with Heat Shield - Infiniti G37 3.7L (2008-2013)

Built for Nissan's Performance Icon

The Infiniti G37 represents the perfect fusion of luxury refinement and genuine sports sedan performance. Its legendary VQ37VHR 3.7L V6—celebrated for its smooth power delivery, high-revving character, and distinctive exhaust note—has earned a devoted following among driving enthusiasts. But the factory intake system holds back that performance, using restrictive components designed for maximum silence rather than breathing capacity.

This cold air intake system transforms your G37's character. Engineered specifically for the 3.7L V6, it replaces the cramped factory airbox with a free-flowing system featuring an integrated heat shield that isolates intake air from engine bay temperatures. The result? Cooler, denser air feeding your engine for up to 10% gains in horsepower and torque, noticeably sharper throttle response, and that aggressive VQ intake sound enthusiasts crave.

Premium Engineering Meets Track-Proven Performance

• Up to 10% Power Increase - Unlock hidden horsepower and torque for stronger acceleration and more spirited driving
• Integrated Heat Shield - Isolates intake air from engine bay heat to maintain consistently cool, dense airflow for optimal performance
• Enhanced Throttle Response - Experience immediate power delivery the moment you touch the accelerator pedal
• Improved Acceleration - Feel stronger mid-range punch for passing power and on-ramp merging
• Aggressive VQ Sound - Deep, sporty intake tone that complements the G37's legendary exhaust note
• T304 Aluminum Construction - Lightweight, corrosion-resistant piping provides thermal resistance and long-term durability
• High-Flow Filtration - Superior airflow without sacrificing engine protection from harmful contaminants
• Low Maintenance Design - Washable, reusable filter requires service only every 50,000 miles under normal conditions

Heat Shield Technology for Consistent Performance

Engine bay temperatures can rob your VQ37 of precious horsepower by reducing air density. This cold air intake system solves that problem with an integrated heat shield that creates a thermal barrier between hot engine components and your intake air. The result is consistently cooler intake temperatures that translate directly to more power, better efficiency, and improved throttle response—especially during spirited driving or hot weather conditions.

The T304 aluminum intake piping eliminates restrictive bends found in factory tubing while resisting heat transfer and corrosion. Combined with the high-flow air filter, this system delivers maximum airflow while maintaining proper sensor placement for smooth, reliable engine operation.

Simple Bolt-On Installation

Transform your G37 in under 60 minutes using basic hand tools. This complete system includes T304 aluminum intake pipe, integrated heat shield, high-flow washable air filter, plus all necessary mounting hardware and clamps. Direct replacement for your factory airbox and intake tube—no cutting or permanent modifications required.

Installation Tip: After completing installation, briefly disconnect your battery to allow the ECU to adapt to the increased airflow and optimize performance parameters. Always ensure the engine is completely cool before beginning work.

Why Upgrade Your G37's Intake System?

Beyond the measurable power gains, this cold air intake delivers benefits you'll appreciate every time you drive: crisper throttle response for more engaging acceleration, a deeper intake tone that announces your presence, a cleaner engine bay appearance, and reduced long-term costs with a reusable filter that eliminates constant replacements.
