COMPATIBLE: (3.0L - VR30DDTT)
2023 - 2025 NISSAN Z RZ34
Wake up your 2023+ Nissan Z with this performance intake system from Mishimoto. The 2022+ Nissan Z sits squarely in the “grand tourer” category with many of its predecessors and rivals. But, if you ask us, modern NVH standards and economies of scale have rendered the Z a little flat. In stock form, you’d be hard-pressed to hear the difference between the Z’s 400 horsepower, twin-turbo, 3.0L V6 and an Altima. But, with a little ingenuity and Mishimoto’s performance intake, you can squeeze more sound, and more power, from your 2023+ Nissan Z.
The Mishimoto 2023+ Nissan Z performance intake gives you the power you expect from your Z with the sound it should have had from the factory. Our intake features a unique convertible design that allows you to quickly switch between closed airboxes for cool intake temps, or open airboxes for serious sound. Switching between the two setups is a simple matter of removing three bands and removing the airbox lid. With open airboxes, the Mishimoto intake system reduces restriction by up to 42 percent, and significantly increased induction sound, while the closed airboxes reduced restriction by 25 percent. The improved flow also results in power gains of over 6 HP and 4.8 lb-ft. of torque with the airboxes closed. Our airboxes also feature enlarged fresh air ducts to ensure cool air for your turbos.
Flow, power, and sound are all great, but they’re useless without safety and reliability. Our airboxes are constructed from rotational-molded XLPE that safely insulates the intake air from engine bay heat. The CNC-machined aluminum MAF housings are precisely designed to ensure accurate and safe readings, even on the stock tune. Finally, our high-flow conical filters increase effective filtration area by 20 percent, ensuring ample flow, without sacrificing clean air. Like all Mishimoto Nissan Z parts, this performance intake kit is backed by our Mishimoto Lifetime Warranty to provide a lifetime of flow, power, and sound.
When Nissan planted the powerful VR30DDTT 3L V6 engine with twin turbochargers in the Nissan Z, there wasn’t much room left in the engine bay. The cramped area didn’t allow enough space to accommodate the traditional top-and-bottom-split airbox design, so they created a unique single-piece airbox with vertically inserted panel filters that maximized flow while minimizing size.
As enthusiasts and engineers, we tipped our hats to appreciate the work Nissan did with this design. But we couldn’t help but ask ourselves—how can we make it even better?
Design Process
Our engineer, Ye, set out to design a direct-fit airbox for the 2023+ Nissan Z with these goals:
• Achieve better airflow than stock
• Ensure a direct-fit, bolt-on installation
• Create a design that lets the user alternate between a sealed or open airbox setup
• Deliver a high-quality intake tone
• Maintain a safe air-to-fuel ratio and ability to run on a stock tune
She began by inspecting and removing the stock airboxes to determine exactly how much space we had for our design. Once we had the measurements, she created a pair of custom-made, oiled high-flow conical filters that increased the effective filtration area by 20%.
Next, Ye had to create a design that allowed for both sealed and open airbox setups. She decided on a unique quick-release setup for the upper half, which uses molded clips and O-ring fasteners with pull tabs to secure the airbox together.
The ability to easily alternate between the two intake styles lets you choose your driving experience. For the cold-air intake setup, leave the upper half of the airbox installed and enjoy the performance benefits. If you’d rather hear your turbo spool and take in more of the Z’s noises, remove that upper half of the airbox and store it somewhere safe.
The MAF (Mass Air Flow) housing is another unique design feature of the stock airbox. Normally, this would be a one-piece design with the housing and airbox molded together. Instead, Nissan designed the housing to be separate and fastened to the airbox with two screws.
This design presented a challenge because the mass air flow curves are specifically calibrated to their original intake systems. Since our air intake increased the airflow, the overall airspeed was faster than stock. If we were to use the stock housing design, the increase in airspeed would throw the MAF calibration off and result in potential check engine lights and pending ECU codes.
To achieve our goal of maintaining a safe air-to-fuel ratio and the ability to run on a stock tune, our airbox comes with two custom CNC-machined MAF housings. Ye verified the success of our housings after many rounds of dyno testing.
Testing and Results
With our 3D-printed prototype in hand, we headed off to run some tests.
Airflow
Using our SuperFlow Dynamics SF-1020, we tested the flow rate of the stock air intake against ours. Since our design is configurable, we separately tested our intake both open and closed.
Both sets of testing indicated that our air intake outperformed stock. The closed configuration was up to 26.5% less restrictive while the open configuration was up to 42.9% less restrictive.
Power
With significantly improved airflow over stock, testing on our Dynapack dynamometer revealed peak gains of 6.39 horsepower and 4.48 foot-pounds of torque.
Tone
Comparing the stock intake to our open-air configuration, we found a terrific improvement in tone. Our engineers were pleased with how the engine sounded and the distinct noise from the turbochargers.
Conclusion
The Mishimoto Performance Intake for the 2023+ Nissan Z is a unique, versatile option for those looking to increase the airflow of their Nissan Z or Nissan Z Nismo and enhance their driving experience. Featuring an easily configurable design that offers two dynamic intake setups, our direct-fit air intake offers improved performance that’s safe to run on a stock tune.
