JDY Billet Intake Manifold - BMW M2 / M3 / M4 / X3 M / X4 M (G8X / F97 / F98 S58)

The JDY Billet Intake Manifold is a fully CNC-machined 6061-T6 aluminium intake for the BMW S58, fitting the G80 and G81 M3, G82 and G83 M4, G87 M2, F97 X3 M and F98 X4 M in both LHD and RHD. Its one-piece 5250cc plenum is 62.4 percent larger than stock, and a CFD-developed internal guide plate corrects the uneven airflow caused by the offset throttle body, raising the airflow uniformity index from 0.781 to 0.880. The modular runners come with an integrated fuel rail for port injection, in Silver, Single MPI (6 Injectors) with an AN8-ORB rail, or Silver, Dual MPI (12 Injectors) with an enlarged AN10-ORB rail, both for Bosch EV14 style injectors. Factory coolant routing, EVAP, engine cover, expansion tank and oil filter access are all retained.

Features

• One-piece billet plenum, 5250cc, with a 4mm wall for rigidity under high boost
• CNC-machined aluminium airflow guide plate welded in place to balance airflow across the cooler and cylinders
• Modular runner section swaps between single and dual MPI without replacing the manifold
• Integrated fuel rail with a 1/8 NPT port for a fuel pressure sensor and plugs for unused injector ports
• 6x top-mounted NPT ports for methanol, nitrous and sensors, plus 2x bottom-mounted NPT ports for boost source or MAP sensor
• Custom thermal isolation gasket (0.25-0.27 W/m K, rated to 250 C continuous) instead of a phenolic spacer
• X-profile FKM (Viton) seals with a stepped male-female sealing interface
• Three stainless steel thread sleeves at the plenum to runner flange for repeated removal
