Eventuri BMW F4X M135i/M235i/128Ti Intake System

Eventuri BMW F4X M135i/M235i/128Ti Intake System is a high-performance intake system engineered specifically for BMW models equipped with the B48 2.0-liter turbocharged four-cylinder engine.

The system is designed to improve the efficiency of the intake airflow by replacing the restrictive factory intake arrangement with Eventuri's patented Venturi filter housing and carbon fiber intake components. Rather than simply fitting a high-flow filter into the original airbox, Eventuri engineers the housing, filter and intake tube as one aerodynamic system.

At the heart of the intake is a Carbon Fiber Venturi Housing surrounding the high-flow filter. The patented housing gradually reduces the cross-sectional area around the filter, helping accelerate airflow and maintain a controlled flow path as air travels toward the turbocharger.

The system also uses a smooth carbon fiber intake tube to create a more efficient route between the filter housing and turbo inlet. The smooth internal surface helps reduce turbulence compared with the convoluted sections commonly found in factory intake systems.

A sealed intake design helps isolate the filter from hot air within the engine bay while allowing the system to draw air through the vehicle's original cold-air feed. This is particularly important on turbocharged engines such as the BMW B48, where maintaining an efficient supply of cooler intake air can support consistent performance.

The Eventuri intake system provides a combination of airflow optimization, reduced intake restriction and improved throttle response, while the carbon fiber construction gives the engine bay a distinctly motorsport-inspired appearance.

The system is suitable for the BMW F40 M135i, BMW F44 M235i Gran Coupe and BMW F40 128Ti, subject to the specific vehicle configuration and Eventuri fitment requirements.
