These OEM filters create a significant pressure drop within the airbox, especially as the V8 climbs toward its high-RPM power band. This restriction results in a \"lazy\" throttle response and prevents the engine from breathing the high-density air required to maximize the combustion cycle of such a large-displacement performance engine.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Engineering Fix:\u003c\/strong\u003e This BMC performance filter replaces the restrictive paper media with a multi-layered cotton gauze soaked in low-viscosity oil. By utilizing an epoxy-coated alloy mesh, we provide a rigid structure that prevents filter deformation under high vacuum. The physics are simple: the cotton fibers allow for a much higher flow rate while capturing impurities as small as 7 microns, ensuring that your AMG receives a higher volume of oxygen-rich air for a sharper throttle snap and a more pronounced V8 induction roar.\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\u003eOptimized Airflow:\u003c\/strong\u003e Significantly reduces air flow constriction compared to OEM paper, allowing the M156 engine to reach its full 500+ HP potential more efficiently.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperior Filtration:\u003c\/strong\u003e Captures impurities down to 7 microns, whereas standard factory filters often only catch particles down to 10 microns, protecting your internal cylinder walls.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRace-Derived Construction:\u003c\/strong\u003e Features a \"Full Moulding\" system with no welded joints, eliminating the risk of breakage or air-leaks even under the extreme heat of an AMG engine bay.\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;\"\u003e2005-2013 Mercedes-Benz AMG Models\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;\"\u003eM156.984 \/ M156.985 \/ M156.983 \/ M156E63 \/ M159.981\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;\"\u003eDimensions\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eB: 308mm | A: 154mm\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\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;\"\u003eFB521\/20\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 CL (C216) CL 63 AMG [2007-2010] - 525 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class C (W204\/C204\/S204) C 63 AMG [2007-Current] - 457 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class C (W204\/C204\/S204) C 63 AMG Black Series [2012-Current] - 517 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class C (W204\/C204\/S204) C 63 AMG Edition 507 [2013-Current] - 507 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class C (W204\/C204\/S204) C 63 AMG Performance P+ [2009-Current] - 487 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class E (W211\/S211) E 63 AMG [2006-2009] - 514 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class E (W212\/S212) 63 AMG [2009-2011] - 525 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class M (W164) ML 63 AMG [2005-Current] - 510 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class R (W251) R 63 AMG [2006-Current] - 510 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz Class S (W221) S 63 AMG [2006-2010] - 525 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLK (A209\/C209) CLK 63 AMG [2006-2007] - 481 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLK (A209\/C209) CLK 63 AMG [2007-2009] - 507 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLS (C219) CLS 63 AMG [2006-2010] - 514 HP\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz SL (R230) SL 63 AMG [2008-2012] - 525 HP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Most of these V8 applications require two (2) filters for a complete installation.\u003c\/p\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\nFB521\/20, M156.984, M156.985, M156.983, M156E63, 156.980, M156.963, M159.981\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 Upgrade your AMG with the same filtration technology used by top-tier racing teams.
