These are the OEM injectors for the S58 engine and the highest flowing injectors of this family from Bosch. In terms of mechanical fitment, they will drop into any B58 Gen2 engine while retaining the correct spray pattern and adding 30% MORE fueling! These injectors combined with our Gen2 HPFP kit are good for just over 700whp on E50 fuel with zero additional fuel system upgrades.

NOTE: You WILL need a tune to properly run these injectors.
