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 \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 \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 \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 \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 \u003cp\u003e\u003cstrong\u003eAlternative Style\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\nKarbonius E9X M3 (S65) Carbon Inlet Plenum and Intake System - Roundel Style (identical performance; Roundel badge in place of \/\/\/M V8 plaque)\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKarbonius E9X M3 (S65) Carbon Plenum Heat Shield Kit\u003c\/li\u003e\n\u003cli\u003eKarbonius E9X M3 Carbon Front Intake Ducts\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Karbonius","offers":[{"title":"2x2 Twill Weave \/ Gloss \/ No","offer_id":47874856419484,"sku":"E92AD02-CF-2-NO","price":4125.0,"currency_code":"USD","in_stock":true},{"title":"2x2 Twill Weave \/ Gloss \/ Yes Include OE \/\/\/M V8 Emblem","offer_id":47874856452252,"sku":"E92AD02-CF-2-YESINCLUDEOE","price":4320.0,"currency_code":"USD","in_stock":true},{"title":"2x2 Twill Weave \/ Matte \/ No","offer_id":47874856485020,"sku":"E92AD02-CFM-2-NO","price":4364.0,"currency_code":"USD","in_stock":true},{"title":"2x2 Twill Weave \/ Matte \/ Yes Include OE \/\/\/M V8 Emblem","offer_id":47874856517788,"sku":"E92AD02-CFM-2-YESINCLUDEOE","price":4559.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Gloss \/ No","offer_id":47874856550556,"sku":"E92AD02-CF-1-NO","price":4284.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Gloss \/ Yes Include OE \/\/\/M V8 Emblem","offer_id":47874856583324,"sku":"E92AD02-CF-1-YESINCLUDEOE","price":4479.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Matte \/ No","offer_id":47874856616092,"sku":"E92AD02-CFM-1-NO","price":4389.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Matte \/ Yes Include OE \/\/\/M V8 Emblem","offer_id":47874856648860,"sku":"E92AD02-CFM-1-YESINCLUDEOE","price":4584.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/3206\/5436\/files\/53712073039_c16a222a2a_b_9835b0d6-b2a5-4d29-adc5-013b864e5e7f.jpg?v=1791774692","url":"https:\/\/daroracing.com\/products\/karbonius-e9x-m3-s65-carbon-inlet-plenum-and-intake-system","provider":"Daro Racing","version":"1.0","type":"link"}
