Genuine Bosch | Part #: 0 280 158 123
Product Overview
The Bosch 0 280 158 123 is a high-performance EV 14 injector featuring the "Standard" (S) body geometry (48.65mm) with an Extended Tip nozzle. This design allows the spray point to reach deeper into the intake runner, bypassing obstructions for improved fuel atomization. Commonly known as the "60lb" injector, it features a Jetronic / EV1 connector and a Type E (Dual Cone) spray pattern.
Visual Check: This specific part number is identified by its Extended Tip and O-ring color combination: Black (Top) and Black (Bottom).
- Flow Capacity: Rated at 57 lb/hr / 597 cc/min (429 g/min) at 300 kPa (43.5 PSI).
- Volumetric Flow: ~627 cc/min (N-Heptane) / ~597 cc/min (Gasoline). *See Tech Note
- Fuel & Seal Compatibility: Features high-quality Viton O-rings (Black/Black) and stainless internals. Fully compatible with E85, Methanol, and Gasoline.
- Electrical Connection: Features a legacy Jetronic / EV1 connector housing.

Technical Note: Flow Rating & Fluids
Bosch calibrates injectors using N-Heptane as a standard test fluid. However, most engines run on Gasoline, which has a higher density. We provide both ratings for transparency:
Volume (cc/min) = Mass Flow (g/min) ÷ Fluid Density (g/cc)- N-Heptane (0.684 g/cc): 429 ÷ 0.684 = 627.2 cc/min (Industry Standard Rating)
- Gasoline (~0.720 g/cc): 429 ÷ 0.720 = 595.8 cc/min (Real World Estimate)
- Factory new Genuine Bosch High-Performance Fuel Injector.
- Factory installed o-rings top and bottom.
- Shipped in factory-sealed Bosch boxes or in bulk bagged format as provided by Bosch.
- Flow Matching: Injectors sold individually ("each") are not flow-matched by Racetronix.
- Absolutely no returns on open-box fuel injectors. Know your application before making your purchase.
*Data Integrity Disclaimer: This specification data is derived from official Bosch technical documentation. We strongly recommend that your tuner verifies all flow and latency (dead-time) data prior to final calibration.
