Where BMW never developed a carbon plenum for the S65 (as they did for the S54 CSL), Karbonius engineered a full carbon fiber intake system — plenum, elbow, airbox cover, and air filter — to improve engine efficiency, unlock a dramatic induction sound, and transform the engine bay aesthetic.\u003c\/p\u003e\n\n\u003cp\u003eDesigned by Karbonius' in-house engineering team using modern 2D and 3D flow analysis, every component has been redesigned to optimize air flow into the engine while minimizing turbulence inside the airbox — delivering measurable power gains alongside the visual and auditory upgrades.\u003c\/p\u003e\n\n\u003cp\u003eEach piece is manufactured from 100% prepreg carbon fiber and autoclave-cured in Spain under ISO 9001 quality standards, combining motorsport-grade construction with authenticity and long-term durability.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCarbon inlet plenum\u003c\/li\u003e\n\u003cli\u003eCarbon elbow\u003c\/li\u003e\n\u003cli\u003eCarbon airbox cover\u003c\/li\u003e\n\u003cli\u003eBMC high-flow air filter (BMC FB536\/08; verify compatibility with your filter cartridge)\u003c\/li\u003e\n\u003cli\u003eInstallation tools\u003c\/li\u003e\n\u003cli\u003eNumbered certificate of authenticity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKarbonius intake (airbox + elbow): 3,635 g vs. OEM 6,677 g — approximately 3 kg weight savings\u003c\/li\u003e\n\u003cli\u003ePower gains: +9 HP with airbox alone; +32 HP with Karbonius airbox + Alpha-N mapping\u003c\/li\u003e\n\u003cli\u003eOptimized internal geometry for improved airflow and reduced turbulence\u003c\/li\u003e\n\u003cli\u003eDramatic S65 V8 induction sound\u003c\/li\u003e\n\u003cli\u003e100% prepreg carbon fiber construction\u003c\/li\u003e\n\u003cli\u003eAutoclave-cured for strength and finish quality\u003c\/li\u003e\n\u003cli\u003eIndividually numbered for authenticity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eAlternative Style\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/ind-distribution.com\/products\/karbonius-e9x-m3-s65-carbon-inlet-plenum-and-intake-system-roundel-style\"\u003eKarbonius E9X M3 (S65) Carbon Inlet Plenum and Intake System - Roundel Style\u003c\/a\u003e (identical performance; Roundel badge in place of \/\/\/M V8 plaque)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/products\/karbonius-s65-carbon-plenum-heat-shield-kit\"\u003eKarbonius E9X M3 (S65) Carbon Plenum Heat Shield Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/products\/karbonius-e9x-m3-prepreg-carbon-fiber-ducts\"\u003eKarbonius E9X M3 Carbon Front Intake Ducts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IND Distribution","offers":[{"title":"2x2 Twill Weave \/ Gloss","offer_id":54549310210331,"sku":"E92AD02-CF-2","price":4125.0,"currency_code":"USD","in_stock":true},{"title":"2x2 Twill Weave \/ Matte","offer_id":54549310243099,"sku":"E92AD02-CFM-2","price":4364.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Gloss","offer_id":54549310275867,"sku":"E92AD02-CF-1","price":4284.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Matte","offer_id":54549310308635,"sku":"E92AD02-CFM-1","price":4389.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/2123\/2667\/files\/53712073039_c16a222a2a_b_95f6c993-c47d-4ada-9f4d-b8aa66199bd4.jpg?v=1794107984","url":"https:\/\/www.sub2speedhouse.com\/products\/karbonius-e9x-m3-s65-carbon-inlet-plenum-and-intake-system-1","provider":"SUB2 SPEEDHOUSE","version":"1.0","type":"link"}
