The UV-protective clear coat is available in gloss or matte over a 2x2 twill or 1x1 plain weave, for a stunning appearance that holds up in any environment.\u003c\/p\u003e \u003cp\u003eBeyond measurable horsepower gains, the Race Airbox delivers sharper throttle response and that unmistakable S54 CSL induction roar — now with built-in cold-air ducting that eliminates the need for a separate snorkel.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCarbon fiber airbox with integrated snorkel\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminum components\u003c\/li\u003e\n\u003cli\u003eStainless-steel hardware\u003c\/li\u003e\n\u003cli\u003eVentilation valve bracket\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\u003eIntegrated snorkel for cold-air ducting from the front of the vehicle\u003c\/li\u003e\n\u003cli\u003eAppreciable gain in power with proper tuning\u003c\/li\u003e\n\u003cli\u003eImproved throttle response and induction sound\u003c\/li\u003e\n\u003cli\u003eAerodynamic, reinforced design at all key points\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\u003eAvailable in 2x2 twill or 1x1 plain weave with a gloss or matte UV-protective clear coat\u003c\/li\u003e\n\u003cli\u003eIndividually numbered for authenticity\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRequired Installation Components (Sold Separately)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\nIND E46 M3 CSL S54 Carbon Airbox Installation Kit\u003cbr\u003e \u003cul\u003e \u003cli\u003eOEM BMW M3 CSL IAT Sensor\u003c\/li\u003e \u003cli\u003eAlpha-N MAF-to-IAT Conversion Harness\u003c\/li\u003e \u003cli\u003eOEM BMW M3 CSL Air Shut-Off Valve\u003c\/li\u003e \u003cli\u003eOEM BMW M3 CSL Crankcase Vent Hose\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOEM BMW M3 CSL SMG Reservoir \u0026amp; Bracket (SMG models only)\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBMW E46 M3 CSL Replacement Air Filter\u003c\/li\u003e\n\u003cli\u003eKarbonius M3 CSL (S54) Carbon Airbox Heat Shield Kit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Karbonius","offers":[{"title":"2x2 Twill Weave \/ Gloss","offer_id":47874864578716,"sku":"E46AD03-CF-2","price":2420.0,"currency_code":"USD","in_stock":true},{"title":"2x2 Twill Weave \/ Matte","offer_id":47874864611484,"sku":"E46AD03-CFM-2","price":2485.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Gloss","offer_id":47874864644252,"sku":"E46AD03-CF-1","price":2485.0,"currency_code":"USD","in_stock":true},{"title":"1x1 Plain Weave \/ Matte","offer_id":47874864677020,"sku":"E46AD03-CFM-1","price":2589.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/3206\/5436\/files\/E46-RaceAirbox-1.jpg?v=1791774700","url":"https:\/\/daroracing.com\/products\/karbonius-e46-m3-csl-s54-carbon-airbox-race","provider":"Daro Racing","version":"1.0","type":"link"}
