Genuine Bosch Motorsport | Part #: 0 280 158 235
Product Overview
The Bosch 0 280 158 235 is a high-performance EV 14 injector featuring the "Standard" (S) body geometry. Unique to this part number is the Denso / Sumitomo connector, making it a drop-in upgrade for many Japanese applications (e.g., Mazda, Toyota, Subaru) without the need for electrical adapters. This injector features a wide 55° Conical Spray for enhanced fuel atomization.
- Flow Capacity: Rated at 66 lb/hr / 731 cc/min (500 g/min) at 300 kPa (43.5 PSI).
- Volumetric Flow: ~731 cc/min (N-Heptane) / ~695 cc/min (Gasoline). *See Tech Note
- Fuel & Seal Compatibility: Features high-quality Viton O-rings (Blue Upper / Blue Lower) and stainless internals. Fully compatible with E85, Methanol, and Gasoline.
- Electrical Connection: Features a Denso / Sumitomo connector housing (Oval with center guide).

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): 500 ÷ 0.684 = 730.9 cc/min (Industry Standard Rating)
- Gasoline (~0.720 g/cc): 500 ÷ 0.720 = 694.4 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. Flow matching is only available on specific pre-packaged sets (packs) when and if available. Purchasing multiple individual units does not guarantee a matched set.
- Absolutely no returns on open-box fuel injectors. Know your application before making your purchase.
*Data Integrity Disclaimer: While we strive for absolute accuracy, some specifications for this part number (such as specific spray angles or OEM-specific O-ring colors) are derived from industry cross-reference data where official Bosch Motorsport documentation is unavailable. We strongly recommend that your tuner verifies all flow and latency (dead-time) data prior to final calibration.
