Eventuri Carbon Fibre Cold Air Intake / Induction Kit for BMW 3 Series G20 B48 2.0 Turbo (318i 320i 330i 330e) – Sealed Heat‑Shielded Carbon Airbox, High‑Flow Performance Intake System – Fits 11/2018+

Carbon intake upgrade for BMW 3 Series G20 2.0 turbo B48 – 318i 320i 330i 330e – from Nov 2018 onward

Unlock sharper response and cool, consistent performance with this premium carbon fibre induction system from Eventuri. Designed for the turbocharged 2.0 petrol B48 found in the 3 Series G20, it replaces the restrictive factory airbox with a sealed, heat‑managed solution that feeds your compressor with denser, cleaner airflow. The result is a purposeful intake note under load, dependable temperatures, and effortless breathing on road or track.

Why it stands out

• Sealed carbon airbox isolates the filter from engine bay heat for cooler charge temps.
• Twin cold feed design including a smart inner‑wing supply to maximise fresh air delivery.
• Gold reflective barrier and integrated shielding to reduce radiated heat near the exhaust side.
• Large‑bore carbon tube begins at 111 mm internal diameter and tapers smoothly to the turbo inlet for low restriction and steady laminar flow.
• Generous airbox volume with a neat recess that accommodates strut brace clearance.
• High‑flow dry element filter, ISO tested for filtration efficiency, with a larger surface area than the OE panel.
• Smooth, optimised flow path from the filter to the compressor inlet for repeatable performance.

What you will notice

• More immediate throttle response and stronger midrange pull.
• Refined turbo spool and induction sound without unwanted cabin drone.
• Stable intake temperatures for reliable, repeatable performance during spirited driving.
• Superb fit and finish that looks as good as it performs.
