Eventuri G01 X3 / G02 X4 M40i (B58D) Black Carbon Intake System

The 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 tape
