Eventuri carbon induction upgrade for BMW 3 Series G20 340i B58 — pre 11/2018 build
Transform response, spool and soundtrack with this premium Eventuri carbon induction system for the 3 Series 340i. Designed to keep charge temperatures stable and airflow smooth, it features a closed carbon airbox, twin feed ducting and a high-volume carbon tube that tapers cleanly to the turbo inlet. The result is cooler, denser air reaching the compressor for consistent performance on spirited road drives and track sessions, plus a purposeful intake note without unwanted cabin boom.
Confirmed fitment
BMW 3 Series G20 340i with the B58 engine built before 11/2018. If you are unsure on compatibility, get in touch and we will confirm fitment for your vehicle.
Key design highlights
- Closed carbon airbox to isolate the filter from engine bay heat for stable intake air temps
- Twin feed design including an additional opening to the wheel arch area for improved airflow supply
- Integrated heat shield with gold reflective layer to reduce radiative heat from the exhaust side
- High-volume smooth carbon tube starting at 111 mm internal diameter and tapering to the turbo inlet for a streamlined path
- Custom high-flow dry filter, ISO tested for filtration with a larger surface area than the factory element
- Airbox maximised for volume with thoughtful clearance for potential strut brace and OE-like mounting
What you will feel

- Reduced heat soak and more consistent performance in traffic and on hot days
