What Makes This Intake Upgrade Exceptional

The do88 Charge Cooler Manifold replaces your factory B58 intake manifold with a fully integrated bar‑and‑plate air‑to‑water intercooler. The precision-machined aluminium unit delivers major gains in airflow, thermal stability, and durability—making it the ultimate plug‑and‑play cooling upgrade for tuned F-series and G-series BMWs.

Factory Limitations Solved

  • The OEM plastic manifold restricts airflow and is prone to cracking at high boost pressures.

  • The factory water‑to‑air charge cooling system quickly heats up under track or spirited use, causing intake air temps to spike and triggering power reduction or limp modes.

  • Port fuel injectors spaced under the OEM design can lead to fuel puddling inside runners—reducing performance and efficiency.

do88’s Intelligent Engineering

  • 102 mm-thick bar‑and‑plate core, increasing water cooling rows from 6 to 11 for superior heat exchange

  • Cast end tanks designed using CFD to ensure even airflow distribution

  • Thermal barrier spacer included—with high-spec FKM-silicone O-rings—to reduce conductive heat transfer from the cylinder head 

  • Designed to fit under the OEM engine cover with bracket support, maintaining engine bay aesthetics on F‑series BMWs such as the 340i (confirmed fit without cover mods on F30/F31) 

Plug & Play with Optional Upgrades

  • Includes integrated sensor pad with three sealed 1/8″ NPT ports (for vacuum or data logging)

  • Each cylinder runner features an individual 1/8″ NPT port—ideal for nitrous or methanol injection (plugged by default) 

  • Designed for auxiliary port injection systems (bracket pre‑cut and ports pre‑threaded) compatible with Injector Dynamics ID1050x or Bosch EV14 setups

  • Exceptionally easy service access: spin‑off oil filter means no need to remove the manifold during oil changes 

Performance & Cooling Gains

  • 42% higher airflow than OEM: 873 CFM vs. 615 CFM at 0.1 bar pressure drop

  • Intake temperatures reduced to ~26 °C vs. 40 °C on stock system

  • Real-world power gains: +5 hp peak (Bootmod3 Stage 2+), +18 hp midrange, +28 Nm torque increase on 340i testing

Compatibility

  • BMW 1 / 2 / 3 / 4 / 5 / 6 / 7 / X3 / X4 MkF/G with B58 Gen 1 engine

  • F20 / F21 M140i, F22 / F23 M240i, F30 / F31 340i, F32 / F36 440i, G01/G02 M40i, G30/31 540i, G32 640i, G11/12 740i etc.

  • Confirmed fit for both stock and tuned B58 variants

Why You Should Upgrade

  • Eliminates heat soak and limp-mode risk on track

  • Robust aluminium construction avoids cracking under boost

  • Compatible with port fuel & meth/nos injection setups

  • Keeps the original engine cover fitment intact

  • Better airflow, lower IATs, and reliable power gains session after session
