APS Tallboy Style Hi Flow Upper Intake Manifold Plenum for Nissan 350Z G35VQ35DE 3.5L
BULL BOOST PERFORMANCE™ presents the Hi Flow Upper Intake Manifold Plenum for Nissan 350Z and Infiniti G35 (VQ35DE). Designed for enthusiasts who want more airflow, more throttle response, and an OEM-plus fitment, this plenum revives the performance legacy of the long-discontinued APS “Tallboy” intake.
For years, the APS Tallboy upper plenum was widely regarded in the Nissan and VQ community as one of the best intake manifold upgrades ever made. It offered increased airflow over the factory unit, stronger mid-range power delivery, and better throttle response without sacrificing street drivability. After APS phased the Tallboy out nearly a decade ago, enthusiasts were left without a high-quality replacement—until now.
The BULL BOOST PERFORMANCE™ Hi Flow Plenum brings that concept back to life with modern manufacturing, improved internal airflow design, and precision fitment that bolts directly in place of your factory plenum. Whether you’re building a high-performance street car, tracking your 350Z/G35, or restoring a classic VQ platform, this intake upgrade delivers measurable gains and a smoother engine feel.
Key Features
Improved Airflow Design
Developed to increase airflow into the engine, improving volumetric efficiency over the stock plenum. Better air volume helps throttle response and mid-range torque.
Inspired by APS Tallboy Engineering
STRATEC™ pays homage to the legendary APS Tallboy plenum with a similar high-flow concept that enthusiasts previously used to unlock extra performance in naturally aspirated and mildly boosted VQ35DE setups.
OEM-Like Fitment
Designed to bolt directly to the stock lower intake and throttle body with no modification required. Retains proper sensor locations and vacuum port compatibility.
Enhanced Throttle Response
With improved internal flow, the engine breathes more easily, translating to sharper throttle feel and reduced restrictions compared to the factory plenum.
Premium Quality Construction
Manufactured from high-grade materials and precision cast for durability, strength, and consistency under daily driving and spirited use.
Straightforward Installation
No cutting, drilling, or special adapters needed. Includes gasket set for a proper seal and easier install.
