2008–2013 Infiniti G37 3.7L VQ37VHR Dual Cold Air Intake
Listed as a dual cold air intake, this Flashark kit is built for the listed VQ37VHR 3.7L applications. It replaces the factory dual intake tracts with two aluminum tubes, two washable cone filters, and two individual heat shields while retaining the engine’s two-throttle-body layout. The open-filter arrangement produces a more noticeable induction sound under acceleration.
Specifications
| Brand | Flashark |
|---|---|
| Engine platform | 3.7L naturally aspirated VQ37VHR V6 |
| Tube layout | Two intake tubes for the factory dual-throttle-body layout |
| Listed tube diameter | 2.75 in / 70 mm |
| Tube material | Aluminum |
| Filter layout | Two washable and reusable cone filters |
| Heat management | Two individual heat shields |
| MAF layout | Retains both factory mass-airflow sensors |
Key Features
- Dual-path design: One tube and filter serve each of the VQ37VHR’s two throttle bodies.
- Smoother aluminum tubing: Replaces the factory corrugated hose and resonator sections in both intake paths.
- Reusable cone filters: Two exposed filters can be inspected and cleaned during routine service.
- Individual heat shields: Each filter area has a separate shield to limit direct underhood radiant heat exposure.
- More audible induction: The open-filter layout creates a deeper intake note under acceleration while cruising remains more subdued at light throttle.
- Factory MAF retention: Both original MAF sensors transfer to the intake tubes; correct orientation and airtight connections remain essential.
Who This Kit Is For
This listed dual cold air intake is for owners of the listed G37, 370Z, and Q50 3.7L VQ37VHR applications who want to replace the factory airboxes and corrugated intake hoses with a dual aluminum-tube layout.
- Drivers who want a more audible intake note under acceleration.
- Owners who are comfortable inspecting and maintaining reusable filters.
- Vehicles that match the listed year, model, engine, body, and drivetrain configuration.
- Not ideal for drivers who want factory-level intake sound and a fully enclosed airbox.
- Not suitable for vehicles that do not use the VQ37VHR 3.7L V6.
- Not recommended for drivers who regularly travel through deep standing water or flooding.
Factory Intake vs. Flashark Dual Intake
| Area | Factory system | Flashark system |
|---|---|---|
| Intake path | Plastic airboxes, resonator sections, corrugated hoses | Two smoother aluminum intake tubes |
| Filter design | Enclosed panel filters | Two washable cone filters with individual heat shields |
| 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 |
Intake Sound and Response
The VQ37VHR uses two throttle bodies, one for each cylinder bank. Keeping two separate intake paths lets each bank draw through its own tube and filter, and the smooth tube interiors remove the ridges found in the factory corrugated hoses. Throttle response and upper-rpm feel depend on vehicle condition, ECU calibration, installation quality, and the rest of the intake and exhaust setup.
Check Before Ordering
- Confirm the exact year, model, engine, body style, and drivetrain in the vehicle selector before purchase.
- Choose the correct configuration. The Cold Air Intake option and the Oil Catch Can + Cold Air Intake option use different SKUs, prices, availability, and package contents.
- Allow the engine to cool before removing factory intake components. Transfer both factory MAF sensors carefully, keep their airflow direction correct, and do not touch or clean the sensing elements unless following the correct sensor-cleaning procedure.
- Seal every coupler and clamp evenly. Keep wiring clear of belts, fans, and hot engine components, then inspect tube, heat-shield, filter, and wiring clearance before starting the engine.
- If the engine idles unevenly or displays a warning light after installation, stop and inspect the MAF connections, sensor orientation, and intake joints for leaks.
- Avoid deep water crossings and direct high-pressure water around the filters; water ingestion can cause hydrolock and severe engine damage.
What's in the Box
Cold Air Intake configuration:
- ✓ Two aluminum intake tubes

The Oil Catch Can + Cold Air Intake configuration has different contents. Review the selected option before installation.
Filter Care and Related Intake Options
Inspect both filters during routine service and more often in dusty conditions. Clean them when dirt buildup is visible, then allow them to dry completely before reinstalling. Browse the Infiniti intake collection, Nissan intake collection, or the broader Air Intake System collection to compare other listed applications.

Infiniti G37 VQ37VHR Dual Cold Air Intake FAQs
Q1: Will this fit my Infiniti G37?
A1: It fits only the listed 3.7L VQ37VHR G37 applications. Confirm the exact year, body style, and drivetrain in the vehicle selector before ordering. G37x owners should contact support or use the selector to verify the AWD configuration.
Q2: Is this a cold air intake?
A2: The current product page lists this configuration as a dual cold air intake. The listed kit replaces both factory intake paths with two aluminum tubes, two cone filters, and two individual heat shields while retaining the dual-throttle-body layout.
Q3: Is this intake legal in my state?
A3: Not legal for sale or use in California (and other CARB-adopting states). Check your local requirements before ordering or installing an aftermarket intake.
Q4: How much horsepower will this add?
A4: Typical intake-only gains for this naturally aspirated application are approximately +3–10 hp and +3–10 lb-ft. Actual results depend on the vehicle, calibration, installation, and supporting hardware.
Q5: Will it improve MPG?
A5: MPG is dominated by driving habits; an intake alone can't guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy.
Q6: Do I need a tune after installing?
A6: No tune is required for a bolt-on install that retains the factory MAF sensors. Correct sensor orientation, sealed couplers, and proper installation remain essential.
Q7: Can it cause a check engine light?
A7: A warning light can occur when a sensor is installed incorrectly, a connector is loose, or unmetered air enters through a leaking joint. Check both MAF connections, sensor orientation, and every coupler if a warning light appears after installation.
Q8: What does it sound like?
A8: You’ll hear a deeper intake tone under acceleration; at cruise it quiets down. Sound is subjective, and the change is generally more noticeable at heavier throttle and higher engine speed.
Q9: Are the filters washable and reusable?
A9: Yes. Inspect both filters during routine service, clean them when visibly dirty, and allow them to dry fully before reinstalling.
Q10: Is it safe in rain or deep water?
A10: Normal wet-weather driving is different from driving through standing water. Avoid deep water crossings and direct high-pressure spraying around the filters because water ingestion can cause hydrolock and severe engine damage.
