In a high-pressure turbo application like the A 45 or CLA 45, the engine struggles to pull air through dense paper fibers as RPMs climb. This creates a significant pressure drop across the filter, forcing the turbocharger to work harder to hit its target boost, which increases intake air temperatures and blunts throttle response during spirited canyon runs or track sessions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Engineering Fix:\u003c\/strong\u003e This BMC performance filter replaces the restrictive factory media with a multi-layered cotton gauze saturated with low-viscosity oil. By utilizing a \"Full Moulding\" production process, the filter is created from a single mold with no welded joints, ensuring structural integrity even under the heavy suction of the AMG twin-scroll turbo. The physics are simple: we are increasing the cross-sectional flow area while improving filtration density. This kit captures impurities as small as 7 microns—surpassing the OEM 10-micron standard—while significantly reducing the resistance in the intake tract for a sharper, more immediate throttle snap.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhy Mechanics Choose This Kit\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Filtration:\u003c\/strong\u003e Captures particles down to 7 microns, providing superior protection for the M133’s sensitive internal components compared to the 10-micron factory limit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Stability:\u003c\/strong\u003e The epoxy-coated alloy mesh protects the cotton media from petrol fumes and oxidation, maintaining its shape and flow characteristics under the extreme under-hood heat of the AMG engine bay.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime Sustainability:\u003c\/strong\u003e Unlike disposable OEM filters that end up in a landfill, this unit is fully washable and regenerable, designed to last the entire lifespan of your vehicle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eFitment\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003e2013-2019 Mercedes-Benz A\/CLA\/GLA 45 AMG\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eEngine Platform\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eM133 2.0L Turbocharged Inline-4\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eFactory Ratings\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003e360 HP \/ 381 HP Variants\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eDimensions (mm)\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eØ1: 158 | Ø2: 67 | L: 189\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003ePart Numbers\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eFB819\/04\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCompatibility \u0026amp; OEM Reference\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFits the Following Vehicles:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMercedes-Benz CLA (C117\/X117) CLA 45 AMG (360 HP) 2013 \u0026gt;\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLA (C117\/X117) CLA 45 AMG (381 HP) 2015 \u0026gt;\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLASS A (W176) A 45 AMG (360 HP) 2013 \u0026gt;\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLASS A (W176) A 45 AMG (381 HP) 2015 \u0026gt;\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz GLA (X156) GLA 45 AMG (360 HP) 2014 \u0026gt;\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz GLA (X156) GLA 45 AMG (381 HP) 2015 \u0026gt;\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eInterchange Part Numbers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"font-family: monospace; font-size: 0.9em; color: #666; background-color: #f5f5f5; padding: 10px; border-radius: 4px;\"\u003e\nFB819\/04, FB819-04\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eThe Performance Promise\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBuy with confidence.\u003c\/strong\u003e We understand the intricacies of the M133 platform.
