BMW F97, F98/ X3M, X4M Performance Turbo Inlet

BMW F97/F98 X3M/X4M Performance Turbo Inlet

Maximise the airflow and performance of your BMW F97 X3M or F98 X4M with this High-Performance Turbo Inlet — engineered to eliminate the restrictions of the factory inlet while improving turbocharger efficiency, throttle response, and induction sound.

Designed specifically for the BMW X3M and X4M equipped with the S58 twin-turbocharged engine, this Performance Turbo Inlet replaces the restrictive factory inlet with a larger, smoother-flowing design that allows the turbochargers to breathe more efficiently. By reducing airflow restriction before the turbochargers, the inlet helps improve turbo spool characteristics, increase airflow, and support higher horsepower applications.

Manufactured from premium CNC-machined aluminium alloy, this turbo inlet is built to withstand the high temperatures and pressures associated with performance driving while providing exceptional durability and corrosion resistance. Whether paired with the factory air intake or an aftermarket intake system, this upgrade provides noticeable improvements in both performance and turbo acoustics.

Perfect for stock vehicles, Stage 1 and Stage 2 builds, or high-horsepower S58 applications.

Key Features

Increased Airflow Design

Larger internal diameter and optimised flow path reduce restriction before the turbochargers for improved engine breathing.

CNC-Machined Aluminium Construction

Manufactured from premium aluminium alloy for superior strength, heat resistance, and long-term durability.

Improved Turbo Efficiency

Allows the turbochargers to spool more efficiently by reducing inlet restriction.

Enhanced Induction Sound

Produces more pronounced turbo spool and induction noises, creating a more engaging driving experience.

Ideal Supporting Modification

Pairs perfectly with aftermarket intakes, charge pipes, downpipes, and ECU tuning for maximum performance.

Direct Bolt-On Installation

Designed specifically for the BMW F97 X3M and F98 X4M using factory mounting locations with no permanent modifications required.
