Product description

Eventuri BMW M340i M440i B58 Gen 3 carbon intake

This Eventuri carbon intake is developed for the 2025+ BMW M340i and M440i with the B58N2 Gen 3 engine. It combines a sealed carbon airbox with a matching inlet tube and a dry high-flow air filter. The set replaces the factory intake with a system designed around the airflow and heat management requirements of this engine generation.

Sealed airbox with dual air feeds

The airbox shields the filter from hot engine-bay air. Alongside the existing air feed, the design uses a second inlet from the wheel arch. A heat shield with a gold-coloured reflective layer helps reduce radiant heat from the exhaust manifold. The airbox also includes a recessed area to provide space around a potential strut brace.

Carbon inlet tube and dry filter

The carbon inlet tube starts with a 111 mm internal diameter and tapers smoothly towards the original turbo connection. Its smooth inner surface replaces the ribbed shape of the factory tube. Eventuri uses prepreg carbon and a purpose-designed dry cone filter with a larger filtration area than the standard filter.

Compatible models

Suitable for 2025+ BMW G20/G21 M340i and G22/G23/G26 M440i, exclusively with B58N2 Gen 3. Check the engine generation before ordering; the model name or model year alone is not enough to identify the correct intake.
