Designed specifically for the B58D engine in the X3 M40i and X4 M40i, this cold air upgrade delivers a smooth, high-volume airflow path while keeping inlet temps low. Ideal for daily drivers and tuned builds alike, this is the air intake upgrade enthusiasts search for when they want genuine performance, stunning looks and OEM-plus fitment.\u003c\/p\u003e\n\n  \u003ch3\u003eWhy enthusiasts choose this intake\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eCooler charge temps thanks to a fully enclosed carbon airbox and advanced heat management\u003c\/li\u003e\n    \u003cli\u003eHigh flow path via a large-bore pre-preg carbon tube that transitions seamlessly to the turbo inlet\u003c\/li\u003e\n    \u003cli\u003eCrisp induction noise and faster turbo spool without drone\u003c\/li\u003e\n    \u003cli\u003ePerfect for BMW tuning, Stage 1 or stock vehicles seeking improved breathing and response\u003c\/li\u003e\n    \u003cli\u003eShowpiece carbon finish that elevates any engine bay\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eEngineered for the B58D powerplant\u003c\/h3\u003e\n  \u003cp\u003eThe M40i’s engine bay gets hot quickly, especially around the exhaust side. Eventuri tackles heat soak head-on with a fully sealed airbox and a dedicated heat shield lined with gold reflective material to minimise radiant heat. The airbox volume is maximised and neatly shaped with a recess so it clears the factory strut brace for a clean, factory-like install.\u003c\/p\u003e\n  \u003cp\u003eThe stock plastic ducting is replaced by a precision pre-preg carbon fibre intake tube with a generous 109 mm internal diameter that progressively narrows to the turbo flange. This maintains air velocity and reduces turbulence for a smooth, unrestricted pathway to the compressor. A bespoke dry cone filter, ISO-tested for filtration performance, provides a larger surface area than the factory element to support increased flow while protecting your engine.\u003c\/p\u003e\n  \u003cp\u003eEvery carbon component is made from 100 percent pre-preg carbon fibre with no fibreglass filler for a smooth internal finish that supports efficient airflow and consistent performance.\u003c\/p\u003e\n\n  \u003ch3\u003eFitment and compatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eChassis: G01 X3 M40i, G02 X4 M40i\u003c\/li\u003e\n    \u003cli\u003eEngine: B58D only\u003c\/li\u003e\n    \u003cli\u003eNot suitable for vehicles with B58 or B58C engines.
