do88 Inlet S58 Manifold BMW G8X M2 M3 M4
Product Description
This upgraded intake manifold has been engineered to deliver a major improvement in airflow, charge cooling and tuning flexibility over the factory setup. With a huge 127mm / 5” Bar & Plate core, the system offers a 62% increase in core size compared with OEM, helping reduce intake temperatures and support consistent performance under sustained load.
The densely packed fin design maximises heat transfer, while the improved core and end tank package delivers a tested airflow increase of 511 CFM at 0.05 bar, compared with 422 CFM for the OEM unit. During testing, intake temperatures were reduced to 28.5°C, compared with 33°C on the factory setup, demonstrating a measurable improvement in cooling efficiency.
The manifold uses CFD-designed cast aluminium end tanks to promote even air and water distribution across the core. This helps improve cooling consistency and reduce pressure drop, supporting more stable performance on tuned road cars, track builds and higher-output applications.
Integrated fuelling and methanol support make the manifold suitable for more advanced setups. An AN8 fuel rail is included, with compatibility for ID1050x-34-14 or Bosch EV14 short injectors. Built-in injector ports and plugs allow for optional port injection, while 1/8” NPT ports on each runner can be used for methanol or nitrous oxide. Three additional 1/8” NPT ports are also included on the outlet for sensor or vacuum reference use.
Thermal management has also been carefully considered. A thick thermal spacer helps reduce heat transfer from the cylinder head, using precision-milled grooves and 12 custom FKM O-rings to create a reliable seal without the need for sealants commonly used in competitor kits.
Despite the additional performance features, the manifold retains full oil filter access and is designed for plug-and-play fitment with no fabrication required. Extensively CFD tested, it is a comprehensive upgrade for owners looking to improve intake temperatures, airflow, fuelling flexibility and long-term reliability.

Most products include a manufacturer’s warranty covering manufacturing defects only. Warranties do not cover wear and tear, improper installation, misuse or neglect, track use, competition or racing environments, labour costs, vehicle damage, downtime, or consequential loss. Warranty outcomes are determined by the manufacturer, not Clubsport Garage. Items must be returned for inspection at the customer’s cost unless agreed otherwise.
Fitment & Installation
Many products are aftermarket components and may require professional installation or minor adjustment. Perfect OEM-level fitment cannot be guaranteed. Professional installation by an experienced workshop is strongly recommended. Installed or used items cannot be returned.
Motorsport Use Disclaimer
Some products are intended for off-road, track, or motorsport use only and may not be legal for road use, for example non-TÜV/DOT-approved parts.
