do88 MERA Charge Cooler Manifold - BMW G-Series B58 (ICM-430-G)

On the B58 the charge cooler lives inside the intake manifold, fed by a small radiator up front. Once the engine is tuned, that system heat-soaks quickly on track or during hard street driving, intake temperatures climb, and the engine computer pulls power or drops into limp mode. do88's manifold replaces the factory unit on G-series cars to keep charge temperatures in check.

What you get

• Replacement intake manifold with integrated charge cooler, built by do88 to fit the dense space the factory part occupies.
• Aimed at tuned engines that see repeated heat soak at the track or in spirited street use.
• MERA version, which comes with do88's auxiliary port-injection fuel rail and the sealing plugs for the crankcase vacuum and fuel tank breather connections.
• Ready for extra fuel. The factory direct injection runs short on flow for big power or ethanol blends, and the included rail sets you up to add port injection.

Good to know

• The separate do88 accessory kit is not needed with this version, since its parts are already in the box.
