034Motorsport P34 Cold Air Intake BMW B58 F Series M140/M240/M340/M440

This cold air intake replaces the factory airbox and plastic intake hose on B58-powered BMW F2X and F3X models with a partially enclosed airbox that reuses the factory fresh air duct and heat shield. It houses a 3.5" inlet conical air filter on a CNC machined billet aluminium velocity stack, with a CFD-optimised 4-ply silicone tube feeding the turbo inlet. 034Motorsport quotes 814 CFM against 674 CFM for the OE intake at 28in H2O, a 21% increase, and says the system improves power, sound and throttle response. The airbox, billet MAF housing adapter, silicone hose, filter and heat barrier tape are all supplied, and it fits at the factory mounting points.
