Mishimoto BMW S58 Inlet Manifold - M2 S58 Charge Air Cooler Manifold Upgrade
Unlock reliable, repeatable power from your BMW S58 with the Mishimoto charge air cooler inlet manifold upgrade. Perfect for the G87 BMW M2 S58 as well as the G8X BMW M3 and BMW M4 platforms, this high-flow intercooler manifold replaces the restrictive and failure-prone factory unit to deliver cooler intake air temperatures, stronger boost handling and rock-solid reliability on the road and track.
We have fitted and used this Mishimoto S58 inlet manifold on customer cars and our own builds at Nforcd. The results are superb, with noticeably lower IATs, faster recovery between pulls and consistent performance in demanding conditions. Customers love the OEM-plus fit and the headroom it unlocks for future tuning, port injection and ethanol use.
Why upgrade your BMW S58 inlet manifold
- Direct fit for 2021+ G8X BMW M3 and BMW M4, and ideal for the S58-powered G87 BMW M2
- Bar-and-plate core TIG welded to a cast aluminium manifold - engineered to withstand over 60 psi of boost
- Core volume is 33 percent larger than stock for enhanced heat rejection
- Average 14 percent better flow to each cylinder for safer, more consistent fueling
- Reduced pressure drop and intake air temps as low as 11 degrees above ambient under heavy load
- CFD-designed lower plenum with internal diverter ensures even flow distribution across the entire core
Port injection ready for big power S58 builds
- Includes billet fuel rail, PTFE -AN lines and fittings - ethanol friendly and E85 suitable
- Precision-drilled injector ports with optimised geometry - no drilling required
- Supplied anodised injector blanks allow easy delete when not using PFI
- Six nitrous ports accept 1/8 or 1/16 NPT nozzles - easily capped when not in use
Built to last, engineered to perform
- Cast and CNC-machined runners with O-ring grooves to accept factory seals
- Included fibre gasket helps insulate runners from engine heat
- Stock-like fit with brackets for tidy wiring and an OEM engine cover mount
- Custom EVAP lines included for a seamless installation
- Convenient plenum cutout provides easy access to the oil filter without affecting flow
The factory S58 combined intercooler and intake manifold is efficient for stock power but is let down by a tube-and-fin core crimped to a thermoplastic plenum. Those crimps are a known weak point, with failures reported at only a few psi over stock. Mishimoto solves this with a robust bar-and-plate core TIG welded to a cast aluminium manifold that takes serious boost in its stride. With bolt-ons, big turbos and a tune, the S58 can push over the 800 hp mark - serious power demands serious cooling, and this manifold is designed to deliver.
