BMW tuned the factory setup for silence, with a small airbox and a resonator-equipped tube that trades flow for quiet. Swap it out and the engine feels sharper and finally sounds like a turbo six.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Carbon Fiber Cold Air Intake fits B58-powered BMW G-chassis models including the G30 540i, G11\/G12 740i, G14\/G15\/G16 840i and the X5, X6 and X7 40i. It flows 506 CFM against 416 CFM for the stock system, a Dinan-tested 20% gain, through an airbox that is 66% larger and a filter with 44% more area.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow the Dinan Carbon Fiber Cold Air Intake Flows More\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe factory intake tube carries a resonator that adds turbulence and restriction on the way to the turbo. Dinan replaces it with a smooth carbon fiber tube and a much bigger box: 250 cubic inches against 150 stock. The washable, reusable pleated cotton gauze filter grows to 82 sq in from 56.75 sq in stock. On a completely stock car, Dinan measured gains of up to 7 WHP and 12 lb-ft at 2500 RPM, right in the rpm range you use every day.\u003c\/p\u003e\n\u003cp\u003eThe intake is real carbon fiber, not a wrap or hydro-dipped plastic. It is also the foundation for Dinan's carbon turbo inlet on these cars. If you want maximum turbo sound later, the Dinan Turbo Inlet D760-0061 and Inlet Fit Kit D763-0100 bolt to this intake. The factory intake will not accept that inlet.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDinan Cold Air Intake Install and Legal Status\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a one-hour bolt-on with no cutting and no tune required, and the gains above were measured on a stock car.
