While high pressure injection molding is more expensive than vac-formed, we are able to achieve a much stronger and better looking product for those who are seeking the ultimate look and performance. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eN\u003c\/span\u003e\u003cspan\u003eACA ducts \u003c\/span\u003e\u003cspan\u003ebring air into a vehicle with minimal increase in drag. \u003c\/span\u003e\u003cspan\u003eThe purpose of a NACA duct is to increase the flow rate of air through it while not disturbing the boundary layer.\u003c\/span\u003e\u003cspan\u003e When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner, but without the drag effects of a plain 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","brand":"Chillout","offers":[{"title":"Clear 4\" duct","offer_id":50522352222373,"sku":"CO-ND14A","price":169.0,"currency_code":"NZD","in_stock":true},{"title":"Carbon 4\" duct","offer_id":50522352255141,"sku":"NP-4","price":389.0,"currency_code":"NZD","in_stock":true},{"title":"Carbon 3\" duct","offer_id":50522360119461,"sku":"NP-3","price":389.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/3099\/0640\/files\/CO-ND14A_0007_7_869x869_916d498f-e9f5-4377-8b96-d8c725a230cc.jpg?v=1790214784","url":"https:\/\/palmside.co.nz\/products\/chillout-naca-duct-4in","provider":"Palmside NZ","version":"1.0","type":"link"}
