Intake Manifold FMIC.Pro for Nissan RB26DETT 2.6L R6 CNC

One of the most advanced and high-performance intake manifolds available for the RB26DETT engine from the FMIC.Pro product line – designed for maximum airflow, high durability and uncompromising high-power builds.
The runners are CNC-machined to increase structural strength and stability.

Conversion: Designed for conversion from the factory ITB system (Individual Throttle Bodies) to a single throttle body setup.

It features a welded aluminum construction with a modular, bolt-together design.
The plenum chamber, runner section and flange are separate components joined with bolts, allowing easy disassembly, servicing and modification depending on engine configuration and boost system setup.

The body is made from high-quality aluminum, precisely welded and CNC-machined to ensure structural rigidity and resistance to high boost pressure and operating temperatures. This solution works perfectly in high-power builds, including big turbo applications.

The intake runner geometry (velocity stacks) and plenum chamber were developed based on CFD analysis, aiming to achieve even airflow distribution across all cylinders, reduce pressure drops and improve flow efficiency under high engine load.

Individually bolted velocity stacks help stabilize and organize airflow, resulting in more consistent cylinder filling and improved utilization of the turbocharging system.

The manifold is designed for high-power RB26DETT builds, both for street and motorsport applications.
