Carbon Fiber MaxFlo Airbox Cover
A carbon fibre Maxflo airbox cover for the Porsche 911 Carrera 997 (2005-2008), replacing the OEM base airbox cover, which Fabspeed says restricts airflow with a built-in muffler baffling the intake. Developed through 3D laser scanning and CAD design, flow-bench tested and dyno proven, it flows 35% more air to the engine, fully filtered, and adds +20hp with a throatier exhaust note even on an otherwise stock car. It's a simple screw-on DIY replacement for the top cover and small MAF housing, using CAD-optimised geometry and stainless steel hardware, taking about 30 minutes to fit. PDK and automatic cars need a vacuum line run to the airbox as part of installation. Carbon fibre construction is autoclaved, and Fabspeed states the design is US EPA, European, and CARB compliant. Either way works: fit it yourself, or let Rennen Motorsport or an authorised dealer handle it.
