BMW actually got the X3M/X4M's intake layout right from the start - the flow path from filters to turbo inlets is direct, without the abrupt direction changes typical of most OEM airboxes. So rather than a wholesale redesign, Eventuri's approach with the Carbon Fibre Intake System V2 was to refine what already works: replacement non-woven mesh filters offering a significantly higher flow rate than the stock paper elements, paired with large carbon fibre scoops positioned behind the front grilles to force more ambient air into the ducts and de-restrict the inlet side of the airbox.
A redesigned prepreg carbon airbox lid replaces the factory plastic component, primarily for engine bay aesthetics but with the side benefit of a more pronounced, refined induction sound. Independent testing has shown a reduction of up to 0.2 seconds in 60-130mph acceleration - a genuine, measurable gain from what was already a well-engineered factory design.
Works with: Stock ECU and factory mounting points - fully compatible with both Pre-LCI and LCI models.
Why Choose This Intake System V2
High-flow non-woven mesh filters - significantly higher flow rate than the restrictive factory paper filters
Carbon fibre scoops behind the front grilles - de-restricts the inlet path and lowers intake air temperatures
Redesigned carbon airbox lid - cleaner engine bay look plus a more refined induction sound
Proven acceleration gain - up to 0.2s faster 60-130mph in independent testing
Compatible with Pre-LCI and LCI models - one system covers the full range
OEM-level fitment - laser-cut stainless steel brackets, factory mounting points, no compromise on quality
