Stock paper filters are notorious for becoming restrictive as they age, effectively \"choking\" the engine during high-RPM pulls and increasing intake temperatures in an already heat-sensitive air-cooled environment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Solution:\u003c\/strong\u003e We utilize BMC’s Formula 1-derived \"Full Moulding\" technology to replace your restrictive factory element. This isn’t just a filter; it’s a precision-engineered performance component that corrects the airflow limitations of the Porsche Air-Cooled Flat-Six, allowing for a higher CFM (Cubic Feet per Minute) throughput while maintaining superior filtration via oil-soaked cotton gauze.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhy This is the Ultimate Upgrade\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eF1-Grade Airflow:\u003c\/strong\u003e Engineered to provide a significantly higher flow rate than OEM paper filters, reducing pumping losses and improving throttle response across the powerband.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Moulding Construction:\u003c\/strong\u003e The filter is produced in a single piece with no welded joints, ensuring the frame won’t crack or leak even when subjected to the extreme engine bay temperatures of an air-cooled Porsche.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWashable \u0026amp; Reusable:\u003c\/strong\u003e Unlike disposable filters that end up in a landfill, this BMC element is fully regenerable using a standard wash and recoat kit, making it the last filter your 911 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;\"\u003e1973-1983 Porsche 911 (T, S, SC)\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;\"\u003ePorsche Air-Cooled Flat-Six\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;\"\u003eApprox. 140 HP - 204 HP \/ 148 LB-FT - 189 LB-FT\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;\"\u003eBMC-032-13, 1973-1983-P911-AF\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\u003ePorsche 911 (1973) - T\u003c\/li\u003e\n  \u003cli\u003ePorsche 911 (1974-1975)\u003c\/li\u003e\n  \u003cli\u003ePorsche 911 (1976-1977) - S\u003c\/li\u003e\n  \u003cli\u003ePorsche 911 (1978-1983)\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\n91111018501, 91111018502, 42202, LX123, BMC-032-13\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 air-cooled performance, we know that every extra CFM counts when you’re pushing a vintage Flat-Six toward redline.
