1.4 T-jet-1.4 Multiair Intake Manifold

1.4 T-Jet / 1.4 MultiAir PERFORMANCE INTAKE MANIFOLD

This performance intake manifold is specifically engineered for 1.4 T-Jet and 1.4 MultiAir engines to support increased airflow demands in upgraded and turbocharged applications. Designed to eliminate the airflow limitations of the factory manifold, it enables the engine to operate more efficiently and unlock higher power potential with improved reliability.

HIGH-EFFICIENCY AIRFLOW DESIGN

OEM intake manifolds on 1.4 T-Jet and MultiAir engines are optimized for stock power levels, emissions compliance, and fuel economy. As turbo size, boost pressure, and engine modifications increase, the factory manifold becomes a significant restriction to airflow and cylinder filling.

This performance intake manifold features optimized runner geometry, smooth internal transitions, and a balanced plenum design that ensure consistent and unrestricted airflow to all cylinders. The result is improved volumetric efficiency, stable combustion, and predictable power delivery across the entire RPM range.

PERFORMANCE BENEFITS

• Improved airflow and cylinder filling under boost

• Noticeable power gains in mid and high RPM ranges

• Faster throttle response and improved drivability

• More stable AFR values under load

• Enhanced consistency in high-performance setups

An essential upgrade for tuned 1.4 T-Jet and 1.4 MultiAir engines, from mild street builds to aggressive performance projects.

OPTIMIZED RUNNER & PLENUM STRUCTURE

The runner length and cross-sectional area are carefully engineered to reduce turbulence while maintaining air velocity. The optimized plenum volume supports steady air supply during rapid throttle transitions and sustained high-load operation, ensuring equal distribution to all cylinders.

MODULAR & INSTALLATION-FRIENDLY DESIGN

The manifold’s modular construction allows compatibility with various throttle body orientations, intercooler piping layouts, and turbo configurations. This flexibility makes it suitable for both OEM-based upgrades and fully custom performance builds.

DURABLE MATERIAL & PRECISION MANUFACTURING

Constructed from a high-temperature and pressure-resistant alloy, the manifold is designed to withstand the demanding conditions of turbocharged engines. Precision CNC machining ensures excellent sealing, accurate fitment, and long-term durability even in high-boost environments.

INTEGRATED VACUUM & SENSOR PORTS

The intake manifold includes integrated ports for clean and secure installation of essential systems such as:

• Boost reference

• MAP sensor

• Fuel pressure regulator

• Blow-off / diverter valve

These ports simplify vacuum routing and provide a professional, reliable engine bay layout.
