The factory turbo inlet carries a resonator whose whole job is to hide the sound of the turbo spooling. It also puts turbulence and restriction right in front of the compressor. If you bought a turbocharged BMW, you probably want to hear it.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Carbon Fiber Turbo Inlet Pipe replaces the factory plastic inlet on B58-powered BMW models, including the F-chassis M240i, 340i and 440i and the G-chassis 540i, 740i, 840i and X 40i models. It removes the resonator, opens the internal diameter by an average of 10.8%, and flows up to 24% more than stock, per Dinan.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat the Dinan Carbon Fiber Turbo Inlet Pipe Changes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe OEM inlet has extra chambers and features that restrict flow and disturb the air on its way to the compressor. Dinan's pipe drops them and gives the turbo a smooth, larger path with 24% more overall volume than the factory part. The result is cleaner air delivery and a lot more turbo sound under throttle. CNC-machined fittings make it a direct replacement for the OEM inlet, and the pipe itself is real carbon fiber, not plastic that cracks with age.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDinan Turbo Inlet Pipe Fitment and Legal Status\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRead this before you order. On F-chassis M240i, 340i and 440i models, this pipe is a direct replacement that works with the factory intake. On B58 G-chassis 5, 6, 7, 8 and X models, it will not mate with the factory intake system. Those cars also need the Dinan Cold Air Intake D760-0068 and the Dinan Inlet Fit Kit D763-0100, both sold separately. It is not legal for sale or use in the State of California and has no CARB Executive Order. Dinan part number D760-0061.
