Eventuri Carbon Fibre Intake System - BMW G01 X3 | G02 X4 M40i (B58)

Compatible only with the B58D motor, not for use in models with B58 or B58C motors (standard B58 version coming soon)

BMW G01 X3 X4 M40

Fitment for the G01 X3 M40i and G02 X4 M40i

The BMW X3 M40i Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures.

In the M40i, the intake system’s proximity to the exhaust manifold poses a challenge, rapidly heating the engine bay. Elevated temperatures compromise engine performance, necessitating a solution that ensures minimal intake air temperatures (IATs). Our solution comprises of a fully sealed intake system, designed to counteract heat soak and prevent the turbo from drawing in heated air.

Moreover, our sealed airbox features a heat shield lined with gold reflective, effectively minimizing radiative heat transfer from the exhaust manifold. To optimize airflow volume, we’ve maximized the airbox size, incorporating a recess to accommodate the strut brace seamlessly.

Replacing the stock convoluted intake tube, our design employs a prepreg carbon tube, boasting a much larger internal volume with an internal diameter of 109mm (4.3″) that seamlessly tapers down to match the turbo inlet, ensuring an uninterrupted airflow path. Complementing this design is a custom-made high-flow dry filter, rigorously tested for ISO-certified filtration performance and boasting a larger filtration area compared to the stock filter.
