do88 BMW B58 Gen 1 (M140I/M240I/340I/440I/540I/X3/X4) Charge Cooler Manifold MERA

MERA, as in "more", means more cooling, better airflow, more performance. Simply, MERA. The B58 Gen 1, introduced with the F-Series, has proven to be a real gem of an engine, capable of high outputs, but the factory plastic intake manifold, with its integrated charge air cooler, becomes a genuine limiting factor once you push beyond stock power. It restricts airflow and poses a real risk of cracking under high boost pressures.

do88's MERA manifold replaces it with a high-performance, motorsport-grade Bar & Plate air-to-water intercooler core from Garrett Motorsport, precisely 102mm (4") thick, delivering 42% more airflow and genuinely lower intake temperatures. Cast aluminium end tanks distribute charge air and cooling water evenly across the core, developed through 3D-scanning, CFD analysis, and 3D-printing iterations, and a thermal barrier spacer insulates the manifold from conductive heat transfer out of the cylinder head. The outlet tank is pre-configured for auxiliary port fuel injection, compatible with Injector Dynamics ID1050x-34-14 or Bosch EV14 Compact (K) injectors, with a matching custom fuel rail available separately. Each cylinder runner also carries a 1/8 NPT port for nitrous or methanol injection, with sealing plugs included if not in use.

Why Choose This Manifold

• Built around a Garrett Motorsport Bar & Plate core, the industry standard for this component
• 42% more airflow than the restrictive OE plastic manifold
• Aluminium construction, genuinely resistant to the OE's known cracking risk under high boost
• Thermal barrier spacer included, reduces conductive heat transfer from the cylinder head
• Pre-configured for auxiliary port fuel injection, with 1/8 NPT ports for nitrous/methanol on each runner
• Easy access to spin-off oil filter, no need to remove the manifold for routine oil changes
