Eventuri G01 X3 / G02 X4 M40i (B58) Black Carbon Intake System
SKU: EVE-GXXB58-CF-INT
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 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.
Each intake system consists of:
- Carbon Fiber Airbox
- Bespoke High Flow Dry Cone Filter
- Carbon Fiber Inlet Tube
- CNC Machined Temperature Sensor Mount
- CNC Machined Breather adapter
- CNC Machined Turbo Flange (both Pre-LCI and LCI versions included)
- Heat Shield with Gold Reflective Backing
- Laser Cut Stainless Steel Brackets
- Silicon Coupler with OEM Specification Clamps
