Tuned, it heat-soaks quickly and the plastic plenum becomes the limit at high boost. The do88 ICM-440-K replaces it with an aluminum manifold built around a 102 mm (4\") bar-and-plate core with 11 water rows against 6 in the factory part.\u003c\/p\u003e\n\u003cp\u003edo88 measured 26 °C intake air temperature against 40 °C for OE under the same conditions, and 873 CFM against 615 CFM at 0.1 bar pressure drop. On a 2017 340i with Bootmod3 Stage 2+ they saw about 5 hp at peak, 18 hp midrange and 28 Nm more torque. A thermal barrier spacer cuts heat from the head, every runner has a 1\/8\" NPT port for methanol or nitrous, a three-port sensor pad is built in, and the outlet tank is prepared for auxiliary port injection. The spin-on oil filter stays accessible. For the fuel rail and extra blanking plugs, add the accessory kit or choose the MERA version, which includes them.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAluminum intake manifold with cast end tanks; replaces the OE plastic manifold\u003c\/li\u003e\n\u003cli\u003eBar-and-plate air-to-water core, 102 mm (4\") thick, 11 water rows (OE: 6)\u003c\/li\u003e\n\u003cli\u003eIntake air temperature: 26 °C vs 40 °C OE (do88 testing)\u003c\/li\u003e\n\u003cli\u003eAirflow at 0.1 bar pressure drop: 873 CFM vs 615 CFM OE — about 42 percent more\u003c\/li\u003e\n\u003cli\u003eMeasured gain on a 340i with Bootmod3 Stage 2+: about 5 hp peak, 18 hp midrange, 28 Nm\u003c\/li\u003e\n\u003cli\u003eThermal barrier spacer with 12 FKM-silicone O-rings\u003c\/li\u003e\n\u003cli\u003e1\/8\" NPT port on each runner; three-port 1\/8\" NPT sensor pad; plugs included\u003c\/li\u003e\n\u003cli\u003ePrepared for auxiliary port injection; fuel rail not included\u003c\/li\u003e\n\u003cli\u003eReplaces OE 11618603913\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003edo88 charge air cooler \/ intake manifold\u003c\/li\u003e\n\u003cli\u003eThermal barrier spacer and 12 × FKM-silicone O-rings\u003c\/li\u003e\n\u003cli\u003e3 × brackets, 3 × silicone hoses, 4 × quick-connect adaptors\u003c\/li\u003e\n\u003cli\u003e3 × engine cover mounting pins and 1 × plastic spacer Ø9\/5.4 × 12 mm\u003c\/li\u003e\n\u003cli\u003e10 cm 8 mm fuel hose\u003c\/li\u003e\n\u003cli\u003eHardware: 7 × M6×30, 2 × M6×25 pin screws, 3 × M6×45, 1 × M5×25, 1 × M5×20, 7 × M5×12, 2 × M5×8, 2 × M6 flange nuts, 7 × M6 spring washers, 4 × M6 washers, 4 × M6 thick washers\u003c\/li\u003e\n\u003cli\u003e2 × cable ties, 4 × mini hose clamps, 2 × hose clamps (20–32 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extras:\u003c\/strong\u003e charge-cooler circuit coolant to refill and bleed after installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired for the optional port-injection setup:\u003c\/strong\u003e the do88 B58 manifold accessory kit (ICM-430-440-KIT, fuel rail and plugs — or choose the MERA version), injectors such as \u003ca href=\"https:\/\/speedlogicauto.com\/products\/injector-dynamics-upgraded-fuel-injectors-for-motorsports-applications-id1050x-id1050xds-id1300x-id1300xds-id1700x-id1700xds-id2600x-id2600xds\"\u003eInjector Dynamics ID1050x\u003c\/a\u003e, fuel supply and a tune: \u003ca href=\"https:\/\/speedlogicauto.com\/products\/bootmod3-b58-bmw-fxx-gxx-m140i-m240i-340i-440i-540i-640i-740i-840i-z4m40i-m340i-x3-m40i-tune\"\u003eBootmod3 B58 Tune – BMW\u003c\/a\u003e or \u003ca href=\"https:\/\/speedlogicauto.com\/products\/mhd-super-license-for-b58\"\u003eMHD Super License – BMW B58\u003c\/a\u003e.
