AMS Performance 80mm Air Intake Kit for RZ34 Nissan Z [AMS.47.08.0003-1]

AMS Performance 80mm Air Intake Kit for RZ34 Nissan Z [AMS.47.08.0003-1]

AMS Performance’s Nissan Z 80mm Air Intakes are engineered to maximize airflow and power on VR30DDTT applications. Oversized 80 mm MAF housings deliver gains up to +30whp over stock, with an average +24whp above 5,000 rpm for a broader, more usable powerband. The open-element design heightens turbo acoustics while out-flowing the factory system, and serviceable dry filters simplify upkeep. Installation is streamlined via precision support brackets, keyed silicone inlet tubes and MAF housings, and detailed instructions. Stock-diameter insert sleeves enable a no-tune setup, while included MAF scaling data and an ECU calibration guide make custom tuning straightforward—yielding sharper throttle response, increased power, and the assertive VR30 character expected from AMS.

The Power of Focused Engineering

• Guided by an engineering-first philosophy, AMS Performance’s Snailworks Engineering Team designed the Nissan Z 80mm Air Intakes with a singular objective: maximum airflow. Featuring the largest-diameter piping and MAF housings available for the VR30 platform, the system stands as the highest-flowing intake on the market. By reducing restriction and pressure drop, the 80mm architecture improves turbo efficiency—delivering cooler compressor outlet temperatures, quicker response, and sustained high-RPM power. Extensive flowbench work and in-car validation confirmed a significant boost in volumetric efficiency, with peak gains of +30whp and an average +24whp above 5,000rpm. This engineering-led approach also preserves precise metering and stable drivability when paired with the provided MAF calibration data.

Slow is Smooth and Smooth is Fast

• AMS Performance’s Snailworks Engineering Team engineered the Nissan Z intake path to keep flow to the twin Garrett turbos as unrestricted and laminar as possible. Optimized MAF housings and silicone couplers create seamless, consistent-area transitions to minimize turbulence and pressure drop, while a radiused filter entry reduces inlet losses. The result is lower restriction, quicker turbo response, and stronger power across the rev range.

More Power

• OEM intake systems often prioritize turbo-noise reduction over airflow, limiting power potential. AMS Performance’s Nissan Z 80mm Air Intakes take the opposite approach—allowing the twin turbos to ingest the air required for maximum performance. Organically shaped inlet tubes are engineered for precise fitment and reduced pre-turbo restriction, using generous bend radii and smooth cross-section transitions to maintain uninterrupted flow to the compressor inlets. Validated by Snailworks Engineering through back-to-back dyno testing against the factory system, the fully open configuration (without stock-sized MAF insert sleeves) produced up to +30whp, with an average +24whp above 5,000 rpm and torque gains across the entire rev range. Averaged across multiple runs for accuracy and repeatability, these results translate to stronger top-end power, improved drivability, and better low-end response—setting the benchmark for airflow and performance on the VR30 platform.

Results That Speak For Themselves

• AMS Performance’s Snailworks Engineering Team benchmarked the OEM intake, a leading competitor, and the AMS 80mm Air Intakes on a state-of-the-art MAF-based flowbench, with MoTeC dash and datalogger capturing data under controlled, real-world–representative conditions. The OEM system reached its limit at roughly 560whp–equivalent airflow, showing about 1.9 psi of depression; the competitor provided only a modest improvement before encountering its own restriction. By contrast, the AMS 80mm system supported the same  560whp at just 1.0 psi of depression—nearly a full psi less than stock—and at equivalent pressure drops it flowed significantly higher than both OEM and competitor. The data is clear: AMS offers the largest, highest-flowing intake solution on the VR30 platform for maximum airflow and horsepower.

Tuner-Friendly by Design

• AMS Performance knows that building the largest, highest-flowing intake is only half the equation; seamless ECU integration completes it. To that end, AMS Performance’s Calibration Team created a dedicated ECU calibration guide for the 80mm Air Intakes. Where oversized competitor MAF housings can cause inconsistent placement, poor orientation, and idle issues, the AMS solution is engineered for precision: support brackets lock the MAF housings and filters, while keyed MAF flanges and keyed silicone turbo inlet hoses ensure repeatable alignment, cutting installation guesswork and calibration time. The guide includes AMS MAF calibration strategies, a Throttle Airflow (TAF) relearn procedure, and radiator fan speed curves, each validated on the dyno and in real-world testing. Calibration data is provided in an easy-to-use Excel format for quick copy-and-paste into common ECU software, delivering stable idle, smooth drivability, and efficient, repeatable calibrations.

Applications

• Nissan Z: RZ34 (2024-Present) [3.0L V6 TT]

Notes

• Install guide available here, optional ECU calibration guide available here
• Included OEM-size MAF sleeves enable no-tune installs. The fully open setup (no sleeves) requires custom ECU tuning.
• Filter performance is easily restored with a quick inside-out blast of 30-40 psi compressed air, no frequent washing needed. For heavy buildup, use a biodegradable cleaner, soak or spray, let it loosen debris, rinse thoroughly, then shake or blow out from the inside and air-dry 24-48 hours.
