{"product_id":"dinan-19-26-bmw-z4-m40i-cold-air-intake","title":"Dinan 19-26 BMW Z4 M40i Cold Air Intake","description":"To achieve the gains in flow that the Dinan intake delivers, the entire lower box of the system, and not just the lid, has been reworked and enlarged in an effort to make use of as much of the available real estate as possible within the engine bay. In turn, this allows a 40% larger, custom, free flowing filter to be housed within and maximum flow to be realized. However, a secondary inlet has always been desired by Dinan to effectively fill the volume of the enlarged air box and increased filter surface area. This desire led to a multitude of experiments being conducted on the effectiveness of a possible open-air inlet in the system. With different shapes, locations, and sizes of openings being tested, the goal was to ensure that the added secondary inlet did not cause any unwarranted side effects such as an increase in air temps in the system. This is commonplace with open-air intake systems where overheated engine bay air is employed in the intake tract. The results of these tests showed that the patterned openings present in the final iteration of the box located on the opposite side from the engine provided a perfect balance of additional volume to assist the factory inlet all the while not causing an increase in turbo inlet temperatures. This was the case regardless of testing conditions (single\/multiple gear pulls, constant speed, 0-100mph runs, etc.).\nSemi-Open - Carbon Fiber - A90\/A91\/G29\n\u003cul\u003e\n  \u003cli\u003eLid includes a brace valley to accommodate factory braces or optional Dinan strut braces\u003c\/li\u003e\n  \u003cli\u003eMore Power: Max gains of 13 WHP and 14 lb-ft of torque on a completely stock vehicle\u003c\/li\u003e\n  \u003cli\u003e40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow\u003c\/li\u003e\n  \u003cli\u003eLarger volume air box (60% larger than stock)\u003c\/li\u003e\n  \u003cli\u003eOutflows factory intake by 58% or more\u003c\/li\u003e\n  \u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n  \u003cli\u003eQuick and easy installation\u003c\/li\u003e\n  \u003cli\u003eImproved throttle response\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade the intake performance and sound of your compatible Toyota GR Supra or BMW Z4 M40i with the Dinan D760-0065 Semi-Open Carbon Fiber Cold Air Intake. Designed to maximize the available space in the engine bay, this system reworks and enlarges the complete lower air box rather than only replacing the lid. The increased housing volume supports a larger, custom free-flowing filter while maintaining a controlled intake path for improved airflow and throttle response.\u003cbr\u003eThe Dinan intake includes strategically patterned openings on the side of the air box opposite the engine. These openings act as a secondary inlet to help fill the enlarged air box and increase available filter volume without introducing the unwanted temperature increases commonly associated with open-air intake systems. Dinan testing across multiple driving conditions, including repeated gear pulls, steady-speed operation, and 0-to-100-mph acceleration runs, demonstrated additional airflow without increasing turbo inlet temperatures.\u003cbr\u003eOn a completely stock vehicle, the Dinan D760-0065 can provide maximum gains of up to 13 wheel horsepower and 14 lb-ft of torque. The filter area is increased by 40 percent compared with the factory design, while the air box volume is 60 percent larger. The system outflows the factory intake by 58 percent or more and produces a louder, sportier induction sound. The carbon fiber lid incorporates a brace valley for compatibility with factory braces or optional Dinan strut braces, and installation is designed to be quick and straightforward.\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cbr\u003e  \u003cli\u003eApplication: 2020-2022 Toyota GR Supra and BMW Z4 M40i applications\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eConstruction: Semi-open carbon fiber intake system\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003ePerformance: Up to 13 WHP and 14 lb-ft of torque on a stock vehicle\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eFilter Area: 40% larger than stock for improved airflow\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eAir Box Volume: 60% larger than the factory housing\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eAirflow: Outflows the factory intake by 58% or more\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eSound: Enhanced, sportier induction note\u003c\/li\u003e\n\u003cbr\u003e  \u003cli\u003eInstallation: Quick and easy installation\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrace-compatible carbon fiber lid with a recessed valley for factory or Dinan strut braces\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDelivers maximum gains of up to 13 WHP and 14 lb-ft of torque on a completely stock vehicle\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProvides a 40% larger filter area than the factory intake\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUses an air box with 60% greater volume than stock\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOutflows the factory intake by 58% or more\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProduces a louder, sportier intake sound\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproves throttle response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for quick and easy installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNot CARB approved\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nBMW Z4 M40i 2022\u003cbr\u003e\nBMW Z4 M40i 2023\u003cbr\u003e\nBMW Z4 M40i 2024\u003cbr\u003e\nBMW Z4 M40i 2025\u003cbr\u003e\nBMW Z4 M40i 2026\u003cbr\u003e\nBMW Z4 sDrive M40i 2020\u003cbr\u003e\nBMW Z4 sDrive M40i 2021\u003cbr\u003e\nToyota GR Supra A91 Edition 2021\u003cbr\u003e\nToyota GR Supra A91 Edition 2022\u003cbr\u003e\nToyota GR Supra Base 2020\u003cbr\u003e\nToyota GR Supra Base 2021\u003cbr\u003e\nToyota GR Supra Base 2022\u003cbr\u003e\nToyota GR Supra Base 2023\u003cbr\u003e\nToyota GR Supra Base 2024\u003cbr\u003e\nToyota GR Supra Base 2025\u003cbr\u003e\nToyota GR Supra Base 2026\u003cbr\u003e\nToyota GR Supra Premium 2020\u003cbr\u003e\nToyota GR Supra Premium 2021\u003cbr\u003e\nToyota GR Supra Premium 2022\u003cbr\u003e\nToyota GR Supra Premium 2023\u003cbr\u003e\nToyota GR Supra Premium 2024\u003cbr\u003e\nToyota GR Supra Premium 2025\u003cbr\u003e\nToyota GR Supra Premium 2026","brand":"Dinan","offers":[{"title":"Default Title","offer_id":67590006079804,"sku":"dnnD760-0065","price":624.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/a8f18164d808c1ceba7b05c4bfc18aa0L.jpg?v=1790564788","url":"https:\/\/necycleshop.com\/products\/dinan-19-26-bmw-z4-m40i-cold-air-intake","provider":"NE Cycle Shop","version":"1.0","type":"link"}
