It's a seamless replacement for the factory OEM unit.\u003c\/p\u003e\n\u003cp\u003eThe OEM plastic turbo inlet is prone to pressure-related cracks and includes a flow-hindering resonator, while its smaller diameter limits performance. MAD's aluminum F-chassis B58 inlet offers a wider diameter and eliminates the factory resonator for smoother, more direct airflow to the turbo, plus an enhanced induction sound.\u003c\/p\u003e\n\u003ch3\u003eKey features \u0026amp; benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAnodized black finish.\u003c\/li\u003e\n\u003cli\u003eBoosts turbo airflow and engine responsiveness.\u003c\/li\u003e\n\u003cli\u003eDurable aluminum construction that outlasts the stock plastic inlet.\u003c\/li\u003e\n\u003cli\u003eRemoves the factory sound resonator for an improved induction note.\u003c\/li\u003e\n\u003cli\u003eMaintains an understated, OEM-style appearance.\u003c\/li\u003e\n\u003cli\u003ePairs with the MAD intake \u0026amp; silicone inlet to remove both resonators completely.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2015+ BMW M140i (F20\/F21, B58)\u003c\/li\u003e\n\u003cli\u003e2017+ BMW M240i \u0026amp; xDrive (F22\/F23, B58)\u003c\/li\u003e\n\u003cli\u003e2016–2019 BMW 340i \u0026amp; 340iX, including GT (F30\/F31\/F34, B58)\u003c\/li\u003e\n\u003cli\u003e2016–2020 BMW 440i \u0026amp; 440iX (F32\/F33\/F36, B58)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eShips from our Vancouver shop — KORE SPEED is proudly Canadian-owned, with no surprise cross-border duties for Canadian buyers.
