Porsche has a long history of restricting engine output with smaller throttle bodies, and this plenum is engineered to overcome that limitation.\u003c\/p\u003e\n\u003cp\u003eThis \"Competition\" model is specifically designed to work in conjunction with an upgraded \u003cb\u003e82mm Porsche GT3 throttle body\u003c\/b\u003e (required and sold separately), replacing the factory 74mm throttle body. This larger diameter allows the engine to inhale more air, especially when paired with a high-performance exhaust system. The more extensive the exhaust system (headers, catalytic converters, and mufflers), the more effective the plenum's performance.\u003c\/p\u003e\n\u003cp\u003eIPD has pioneered a new design with the Competition Carrera Plenum, featuring a unique and innovative internal merge collector area. This advanced design significantly enhances laminar flows and volumetric efficiencies, resulting in not only impressive power gains but also a more linear power delivery and improved throttle response.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eRequires an Upgraded Throttle Body:\u003c\/b\u003e This plenum requires the use of an 82mm Porsche Throttle Body (available at an additional charge).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eAdvanced Design:\u003c\/b\u003e Features a unique internal merge collector for enhanced laminar flows and volumetric efficiencies.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePerformance Focus:\u003c\/b\u003e Designed to work optimally with high-performance exhaust systems for maximum power and torque.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePerformance Gains:\u003c\/b\u003e Delivers noticeable and impressive gains, though exact figures will vary depending on existing modifications.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eECU Adaptation:\u003c\/b\u003e Full power improvements are realized once the factory ECU\/DME completes its necessary \"adaptation.\" This can be expedited with spirited, full-throttle runs on a closed course\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IPD","offers":[{"title":"Default Title","offer_id":40970359275578,"sku":"NR99669","price":949.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4846\/2650\/files\/Competition-Intake-Plenum-911-1999-2004-1.png?v=1754693645","url":"https:\/\/sierramadrecollection.com\/products\/competition-intake-plenum-911-1999-2004","provider":"Sierra Madre Collection","version":"1.0","type":"link"}
