{"product_id":"e60-m5-one-piece-carbon-plenum","title":"E60 M5 One Piece Carbon Plenum","description":"\u003cp\u003eOne of the most challenging intake systems Infinity Design has designed and manufactured to date, and the brand's showcase product. The BMW E60 M5 CSL has always captivated S85 owners, its centrepiece being the single-piece carbon plenum with larger side inlets running AlphaN software — a part that was never available to buy. Rather than make another carbon plenum that simply replaces the OEM for noise alone, Infinity Design went the extra distance to give enthusiasts something special for one of the last truly great naturally aspirated engines.\u003c\/p\u003e\u003cp\u003eThe 100% pre-preg carbon fibre plenum was designed in CAD using accurate 3D scans of the engine and engine bay without the OEM plenum in place, and of both individual OEM plenums, then combined into a single larger-volume plenum. At the core of the design is its modularity — key to functionality, fitment, multiple upgrade paths and a lower price.\u003c\/p\u003e\u003ch3\u003eOEM \u0026amp; CSL Side Inlets\u003c\/h3\u003e\u003cp\u003eIn OEM side-inlet form the plenum fits the OEM intake (or any intake that fits the OEM plenum), and can later be upgraded by fitting the larger CSL intake kit. The CSL side inlets are over 100% larger in cross-sectional area than OEM, allowing maximum airflow, and form part of the full CSL intake kit, which can be bought from the outset or added later.\u003c\/p\u003e\u003ch3\u003eVelocity Stacks \u0026amp; Throttle Body Adapters\u003c\/h3\u003e\u003cp\u003eTen carbon velocity stacks with aluminium base plates are supplied — similar to OEM but with a 10% larger opening and reoriented to face the inlets. Ten CNC-machined throttle-body adapters fit from below the plenum and bolt through the carbon into the velocity stacks for a strong, thorough seal.\u003c\/p\u003e\u003ch3\u003ePerformance \u0026amp; Sound Testing\u003c\/h3\u003e\u003cp\u003eThe induction sound is beyond anything else on the market. Multiple reports from the initial pre-production batch showed more usable torque, improved 60–130 mph times and improved power on dyno testing, with sensational under-bonnet looks.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e100% pre-preg carbon fibre construction\u003c\/li\u003e\n\u003cli\u003eModular design with OEM or CSL side-inlet options\u003c\/li\u003e\n\u003cli\u003e10 carbon velocity stacks with 10% larger openings\u003c\/li\u003e\n\u003cli\u003e10 CNC-machined throttle-body adapters\u003c\/li\u003e\n\u003cli\u003eDramatically enhanced induction sound and more usable torque\u003c\/li\u003e\n\u003cli\u003eAlphaN ECU tuning required\u003c\/li\u003e\n\u003cli\u003eDirect OEM fitment; gloss or matte carbon finish\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Infinity Design","offers":[{"title":"Gloss Carbon \/ Full CSL Intake \/ + ECU Tune","offer_id":49607538376842,"sku":"INF-S85-P-GFE","price":9004.0,"currency_code":"NZD","in_stock":false},{"title":"Gloss Carbon \/ Full CSL Intake \/ No ECU Tune","offer_id":49607538409610,"sku":"INF-S85-P-GFN","price":8464.0,"currency_code":"NZD","in_stock":false},{"title":"Gloss Carbon \/ OEM Intake \/ + ECU Tune","offer_id":49607538442378,"sku":"INF-S85-P-GOE","price":5402.0,"currency_code":"NZD","in_stock":false},{"title":"Gloss Carbon \/ OEM Intake \/ No ECU Tune","offer_id":49607538475146,"sku":"INF-S85-P-GON","price":4862.0,"currency_code":"NZD","in_stock":false},{"title":"Matte Carbon \/ Full CSL Intake \/ + ECU Tune","offer_id":49607538507914,"sku":"INF-S85-P-MFE","price":9004.0,"currency_code":"NZD","in_stock":false},{"title":"Matte Carbon \/ Full CSL Intake \/ No ECU Tune","offer_id":49607538540682,"sku":"INF-S85-P-MFN","price":8464.0,"currency_code":"NZD","in_stock":false},{"title":"Matte Carbon \/ OEM Intake \/ + ECU Tune","offer_id":49607538573450,"sku":"INF-S85-P-MOE","price":5402.0,"currency_code":"NZD","in_stock":false},{"title":"Matte Carbon \/ OEM Intake \/ No ECU Tune","offer_id":49607538606218,"sku":"INF-S85-P-MON","price":4862.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4599\/4122\/files\/53501171418_2e43856d87_k_6bde1cd9-790e-4ef5-b354-dccc20801480.jpg?v=1782662062","url":"https:\/\/qjipdu-tf.myshopify.com\/products\/e60-m5-one-piece-carbon-plenum","provider":"SBX Performance","version":"1.0","type":"link"}
