Mishimoto S58 Charge Air Cooler Inlet Manifold for BMW G87 M2, G80/G81 M3, G82/G83 M4 Port Injection Ready PFI Fuel Rail Bar-and-Plate Intercooler Manifold Upgrade

BMW S58 Intake Plenum and Integrated Charge Cooler Upgrade by Mishimoto

Transform the way your G87 M2, G80 or G81 M3, and G82 or G83 M4 responds to heat and boost with Mishimoto’s high-efficiency intake plenum and integrated charge cooler. This direct-fit system delivers colder charge temps, stronger boost stability and dependable performance for spirited road use, track days and high-power builds. If you are chasing consistent power, quicker heat recovery and tuning headroom, this is the proven solution.

Installed and tested by MJ Modifications in Warwickshire, this unit has impressed us and our customers with noticeably lower inlet temperatures, rapid recovery between pulls and repeatable results on hard drives. The fit is OEM-like, the quality is excellent and it unlocks the overhead needed for ethanol blends, hybrid turbos and serious mapping.

Key performance gains

• Dense bar and plate core welded to a cast aluminium plenum for serious boost control - engineered to handle over 60 psi
• 33 percent increase in core volume for superior heat rejection under sustained load
• Per-cylinder airflow improved by an average of 14 percent for safer, more consistent fuelling
• Lower pressure drop with intake temps recorded as little as 11 degrees above ambient during heavy use
• CFD-optimised lower plenum with an internal diverter that evens out distribution across the entire core

Port fuel injection ready for big power

• Billet aluminium fuel rail with PTFE -AN hoses and fittings - fully compatible with ethanol and E85
• Pre-machined injector bosses with optimised angle - no drilling required
• Anodised blanks supplied for easy deletion when not running port fuel injection
• Six auxiliary ports accept 1/8 or 1/16 NPT nozzles for nitrous or meth - easily capped when not in use

Built to last

• Cast and CNC-machined runners with O-ring grooves to accept factory seals
• Included fibre gasket helps reduce heat transfer into the runners
• Stock-style mounting with tidy loom brackets and provision for the OE engine cover
• Custom EVAP lines supplied for a clean, straightforward install
• Convenient service window in the plenum for easy oil filter access without affecting flow

Why replace the factory unit

The original combined cooler and intake is efficient at standard output but relies on a tube and fin core crimped to a thermoplastic shell. Those crimps are a known weak point and can fail with only mild increases in boost. Mishimoto’s welded bar and plate core bonded to a robust cast aluminium plenum removes that risk. With bolt-ons, upgraded compressors and calibration, the S58 is capable of 800 hp-plus. Serious power needs serious charge temperature control and this manifold is built for the job.
