This creates a significant bottleneck for the EA113 1.8T and 2.0 TFSI engines, which rely on rapid spooling, and the 4.2L V8, which requires massive air volume at high RPM. Stock filters typically only trap particles down to 10 microns, often sacrificing airflow for filtration density.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Solution:\u003c\/strong\u003e This BMC performance filter replaces the restrictive stock element with a high-flow, multi-layered cotton gauze media. By utilizing a \"Full Moulding\" system, we provide a filter with no welded joints, eliminating the risk of breakage or air bypassing the media. This setup allows for filtration down to 7 microns while significantly increasing the CFM (Cubic Feet per Minute) capacity of the intake tract.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhy This is the Essential Induction Upgrade\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced Filtration:\u003c\/strong\u003e Captures impurities as small as 7 microns, outperforming the standard 10-micron OEM paper filters while maintaining superior airflow.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Moulding Construction:\u003c\/strong\u003e Engineered from a single mould with no welded joints, ensuring the red rubber housing fits perfectly within the factory airbox without air leaks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWashable and Reusable:\u003c\/strong\u003e Unlike disposable paper filters, this cotton gauze media can be regenerated using a standard cleaning kit, making it the last filter your Audi will ever need.\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;\"\u003e2001-2008 Audi A4, S4, RS4 (B6\/B7 Chassis)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eEngine Family\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eEA113 (I4), 3.0\/3.2 V6, and 4.2L V8 (BBK\/BNS)\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;\"\u003e102 HP to 420 HP (Model Dependent)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0; font-weight: bold;\"\u003eConstruction\u003c\/td\u003e\n    \u003ctd style=\"padding: 10px; border: 1px solid #e0e0e0;\"\u003eEpoxy-Coated Alloy Mesh with Multi-Layer Cotton Gauze\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\u003eAudi A4 + Cabriolet (B6\/B7) 1.6 (2001-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 1.8 T 150HP\/163HP\/170HP\/190HP (2000-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 1.9 TDI 100HP\/115HP\/130HP (2000-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.0 130HP (2000-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.0 FSI 150HP (2002-2005)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.0 TDI 125HP\/140HP\/170HP (2004-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.0 TFSI 170HP\/200HP\/220HP (2004-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.4 V6 163HP\/170HP (2001-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.5 TDI V6 155HP\/164HP\/180HP (2000-2005)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 2.7 TDI V6 163HP\/180HP (2005-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 3.0 TDI V6 204HP\/233HP (2004-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 3.0 V6 220HP (2000-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 3.2 FSI 256HP (2004-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 4.2 V8 RS4 Quattro 420HP (2005-2008)\u003c\/li\u003e\n  \u003cli\u003eAudi A4 + Cabriolet (B6\/B7) 4.2 V8 S4 Quattro 344HP (2002-2008)\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\n8E\/8H, B6, B7, 8E0129620, 8E0129620A, BMC-FB254\/01\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 As specialists in the VAG (Volkswagen Audi Group) platforms, we understand the nuances of the B6\/B7 chassis.
