Infiniti G37 and Nissan 370Z Dual Cold Air Intake
A smoother intake path and a more noticeable induction sound can make the VQ37VHR feel more responsive when the engine is worked through the upper rev range. This Flashark dual cold air intake is designed for listed Infiniti G37, Nissan 370Z, and Infiniti Q50 3.7L applications using the naturally aspirated VQ37VHR engine.
The system replaces both factory intake tracts with two aluminum tubes, two cone filters, and two heat shields. Each tube supplies one of the engine’s two throttle bodies, retaining the factory dual-intake layout rather than combining both banks into a single pipe.
Specifications
| Brand | Flashark |
|---|---|
| Product Type | Dual cold air intake kit |
| Engine Platform | VQ37VHR 3.7L naturally aspirated V6 |
| Tube Layout | Two intake tubes for the factory dual-throttle-body layout |
| Listed Tube Diameter | 2.75 inches / 70 mm |
| Tube Material | Aluminum |
| Filter Layout | Two washable and reusable cone filters |
| Heat Management | Two heat shields |

Key Features
- True dual-intake layout: Two separate intake paths feed the VQ37VHR’s two throttle bodies.
- Smoother tubing: Aluminum tubes replace the factory corrugated intake hoses and resonator sections.
- Reusable filters: Two cone filters provide a larger exposed filtering area than the factory panel-filter layout.
- Dual heat shields: A separate shield surrounds each filter area to reduce direct exposure to underhood radiant heat.
- More audible induction sound: The open-filter arrangement produces a deeper intake note under acceleration while remaining less pronounced at light throttle.
- Factory MAF retention: Both original MAF sensors transfer to the intake tubes. Correct sensor orientation and airtight connections are important during installation.
Built for Throttle Response and Intake Sound
The VQ37VHR uses two throttle bodies, one for each cylinder bank. Keeping two separate intake paths allows each bank to draw through its own tube and filter. The smooth tube interiors also remove the ridges found in the factory corrugated hoses.
The most noticeable change is the intake sound. Light-throttle cruising remains more subdued, while heavier throttle produces a deeper induction note. Throttle response and upper-rpm feel depend on the vehicle’s condition, ECU calibration, installation quality, and the rest of the intake and exhaust setup.
Factory Intake vs. Flashark Dual Intake
| Area | Factory System | Flashark System |

| Filter design | Enclosed panel filters | Two washable cone filters |
| Sound | Resonators suppress induction noise | Deeper intake sound under acceleration |
| MAF sensors | Two factory sensors | Reuses both factory sensors |
| Heat shielding | Factory enclosed airboxes | Individual shields around the filter areas |
Configuration and Package Contents
Cold Air Intake
- Two aluminum intake tubes
- Two cone air filters
- Two heat shields
Oil Catch Can + Cold Air Intake
This configuration combines the dual cold air intake with an oil catch can. Package contents vary by selected configuration. Select the required SKU before ordering and check the selected configuration before installation.
Configuration reminder: The cold air intake and the oil catch can plus cold air intake use different SKUs, prices, and package contents. Check the selected option in the purchase area before adding the product to your cart.
Installation Notes
- Allow the engine to cool before removing the factory intake components.
- Transfer both factory MAF sensors carefully and install them in the correct airflow direction.
- Do not touch or clean the MAF sensing elements unless the correct sensor-cleaning procedure is being followed.
- Check every coupler and clamp for an even, airtight seal.
- Keep wiring clear of belts, fans, and hot engine components.
- After installation, inspect the tubes, heat shields, filters, and wiring for clearance before starting the engine.
- If the engine idles unevenly or displays a warning light, stop and inspect the MAF connections, sensor orientation, and intake joints for leaks.
Filter Care and Water Precautions
Inspect both filters during routine service and more frequently in dusty conditions. Clean the filters when dirt buildup becomes visible and allow them to dry completely before reinstalling them.
Avoid driving through deep standing water or directing high-pressure water at the filter areas. No open-filter intake system should be treated as protection against flooding or water ingestion.
Who This Intake Is Best For
- G37, 370Z, and Q50 3.7L owners who want a more audible intake note.
- Drivers replacing the factory airboxes and corrugated intake hoses with a dual aluminum-tube layout.
- Owners who are comfortable inspecting and maintaining reusable filters.
- Vehicles that match the listed year, model, engine, body, and drivetrain configuration.
Who Should Choose Another Option
- Drivers who want factory-level intake sound and an entirely enclosed airbox.
- Vehicles that do not use the VQ37VHR 3.7L V6.
- Owners who cannot identify the correct Sedan, Coupe, RWD, AWD, or G37x configuration.
- Drivers who regularly travel through deep standing water or flooding.
- Buyers who require a guaranteed horsepower increase, guaranteed fuel-economy improvement, or an unconditional no-CEL promise.

Infiniti G37, Nissan 370Z and Q50 Cold Air Intake FAQs
Q1: Does this intake fit every Infiniti G37?
A1: No. The vehicle must use the 3.7L VQ37VHR engine and match the listed year and configuration. Check whether your G37 is a Sedan or Coupe and whether it is RWD or AWD before ordering. G37x owners should use the vehicle selector or contact customer support.
Q2: Does it fit both G37 Sedan and Coupe models?
A2: Body style can affect installation details. Select the exact vehicle configuration instead of ordering by engine size alone.
Q3: Is this an Infiniti G37x cold air intake?
A3: G37x models use AWD, so the exact drivetrain and body configuration must be checked in the vehicle selector. Do not assume that a RWD G37 application automatically covers the G37x.
Q4: Why does the kit use two intake tubes?
A4: The VQ37VHR has two throttle bodies, one for each cylinder bank. The kit retains that layout with one tube and filter for each side of the engine.
Q5: Will the intake change the sound of my G37 or 370Z?
A5: Yes. The cone filters and reduced resonator volume produce a deeper induction sound under acceleration. The change is usually most noticeable at heavier throttle and higher engine speed.
Q6: Does this cold air intake require an ECU tune?
A6: The kit retains the two factory MAF sensors. Correct sensor orientation, coupler sealing, and tube installation are essential. Modified vehicles or vehicles with unusual fuel trims should be evaluated by a qualified technician.
Q7: Can the intake cause a Check Engine Light?
A7: Any MAF-based intake can produce a warning light if a sensor is installed incorrectly, a connector is loose, or unmetered air enters through a leaking joint. Inspect both MAF connections and every coupler if a warning light appears after installation.
Q8: How much horsepower does the intake add?
A8: Results vary with the vehicle, ECU calibration, engine condition, ambient temperature, and installation quality. A fixed horsepower increase should not be expected without a same-vehicle before-and-after dyno test.
Q9: Will it improve fuel economy?
A9: Fuel economy depends heavily on driving style, traffic, vehicle condition, and ECU fuel correction. The intake should not be purchased on the expectation of a guaranteed MPG improvement.
Q10: Are the filters washable and reusable?
A10: Yes. Inspect both filters during routine service, clean them when visibly dirty, and allow them to dry fully before reinstalling them.
Q11: Is the intake safe to use in heavy rain?
A11: Normal wet-weather driving is different from driving through standing water. Avoid deep water, flooding, and direct high-pressure spraying around the filters because water ingestion can damage an engine.
Q12: Can I install the kit at home?
A12: The work involves removing both factory intake paths, transferring two MAF sensors, positioning the heat shields, and checking all connections for leaks and clearance. A capable DIY owner can perform the work with suitable hand tools, but professional installation is recommended when MAF handling or fitment is unfamiliar.
Q13: What is the difference between the two purchase options?
A13: One configuration contains the dual cold air intake. The other combines the intake with an oil catch can. The options use different SKUs, prices, availability, and package contents, so check the selected configuration before ordering.
Q14: Who should not buy this intake?
A14: It is not a suitable choice for vehicles outside the listed VQ37VHR applications, buyers who cannot identify their body and drivetrain configuration, or drivers who want factory intake sound and a fully enclosed airbox.
