Under sustained boost, this dense media induces an intake pressure drop across the turbo inlet tract. Paper elements absorb atmospheric moisture, which swells the wood pulp fibers and further chokes airflow. This restriction forces the turbocharger to work harder to hit target boost pressures, increasing intake air temperatures (IATs) and dampening low-end throttle response.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThe BMC filter utilizes multi-layer surgical cotton gauze saturated with low-viscosity synthetic oil, retained by an epoxy-coated alloy mesh. This oiled cotton matrix traps contaminants down to 7 microns without choking laminar flow into the compressor wheel. Encased in a single-piece molded polyurethane frame without welded corners, it prevents blow-by and seals airtight against the OEM airbox housing. The filter is fully washable and regenerable, resisting high engine-bay heat soak without deformation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFilters per kit\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e135mm x 362mm panel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBMC FB939\/20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility \u0026amp; OEM Reference\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFits the following vehicles (BMC fitment data):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.0 Turbo MultiAir (200 HP) | 2016-2022\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.0 Turbo MultiAir (280 HP) | 2016+\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet (136 HP) | 2015+\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet (150 HP) | 2016-2017\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet (180 HP) | 2016-2018\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet AT8 (160 HP) | 2018-2020\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet AT8 (190 HP) | 2018-2020\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet AT8 (210 HP) | 2016+\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.2 MultiJet AT8 (150 HP) | 2016-2018\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Giulia (952) 2.9 V6 Quadrifoglio AT8 (510 HP) | 2016-2023\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.0 Turbo MultiAir (201 HP) | 2017-2022\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.0 Turbo MultiAir (280 HP) | 2017+\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.2 Diesel (150 HP) | 2016-2018\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.2 Diesel (180 HP) | 2017-2018\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.2 Diesel (210 HP) | 2017+\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.2 Diesel (160 HP) | 2018-2020\u003c\/li\u003e\n\u003cli\u003eAlfa Romeo Stelvio (949) 2.2 Diesel (190 HP) | 2018-2022\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Cross Reference (BMC):\u003c\/strong\u003e FIAT GROUP 50534420\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Type 952 and Type 949 Giulia \u0026amp; Stelvio?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the Alfa Romeo Giulia and Stelvio equipped with the \u003cstrong\u003eGME-T4 2.0L Turbo\u003c\/strong\u003e engine.
