Precision Raceworks S58 / B58 Gen 2 High Flow Direct Injectors – BMW & Toyota GR Supra

OVERVIEW

High flow direct injectors for the S58 and the second-generation B58, rated for 350 bar fuel pressure at the rail with tolerance for normal overpressure. They are about 26 percent larger than the stock S58 injector and 60 percent larger than the stock B58 Gen 2 injector, which is what a Gen 2 car needs once it has run out of injector before it has run out of turbo.

They are a direct fit: no harness adapters and no spacers. Ethanol compatible, with an OEM-equivalent 8-hole spray geometry so combustion stays where the factory calibration expects it. Every injector is tested statically and dynamically, batch matched to plus or minus 2 percent, and checked for Pmax operation and fine leaks.

A tune is required. The set ships with a tuning guide carrying injector data for EcuTek, MHD and Bootmod3.

Notes

• S58 fitment (M2 G87, M3 G80, M4 G8x, X3 M / X4 M F97 / F98) is per Precision Raceworks' injector sizing — the injectors are rated 26% larger than the stock S58 unit. The vendor's published fitment tab lists only the B58 Gen 2 cars; confirm with Speed Logic if your S58 car is a 2025+ model.
• B58 Gen 2 and S58 only. First-generation B58 engines (250 bar system) take the Precision Raceworks B58 Gen 1 Upgraded Direct Injectors (201-0425 / 201-0426).
• These replace the factory direct injectors; they are not supplemental port injection injectors.
• Confirm your engine code and generation before ordering.
• Price is for the set only; labor and tuning are not included.
