Used in conjunction with 4-inch Neoprene Air Duct Hose and a 4-inch Chillout Carbon Fiber Plenum (both available in the drop downs above), the Chillout Carbon Fiber NACA Duct results in maximum cooling efficiency for your cooling system.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\" font-size: large; color: #333333;\"\u003eNACA ducts bring air into a vehicle with a minimal increase in external drag. The purpose of a NACA duct is to increase the flow rate of air while not disturbing boundary layer airflow over your vehicle's exterior. When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner (without the drag effects of a standard scoop). The reason why the duct is narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area slowly so that airflow doesn’t separate and cause turbulence and drag.\u003c\/span\u003e\u003c\/p\u003e\r\n\u003ch3\u003e\n\u003cspan style=\" font-size: large; color: #333333;\"\u003e\u003c\/span\u003e\u003cspan style=\" font-size: large; color: #000000;\"\u003eFEATURES:\u003c\/span\u003e\n\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\" font-size: large; color: #333333;\"\u003eDry carbon fiber for light weight and durability.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\" font-size: large; color: #333333;\"\u003eWind tunnel tested.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\" font-size: large; color: #333333;\"\u003e55% more airflow than 3\" NACA duct.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cdiv\u003e\u003cspan style=\"color: #333333;  font-size: large;\"\u003eChillout Cooler sold separately.\u003c\/span\u003e\u003c\/div\u003e","brand":"Competition Motorsport","offers":[{"title":"Default Title","offer_id":43141998116927,"sku":"CO-NP-4","price":192.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/1143\/7631\/files\/chillout-systems-4-carbon-fiber-naca-duct-641855.jpg?v=1776467469","url":"https:\/\/www.spicycatracing.com\/products\/chillout-systems-4-carbon-fiber-naca-duct","provider":"Spicy Cat Racing","version":"1.0","type":"link"}
