Fitment Notes

• Universal top-feed injector - confirm O-ring seat diameter (14mm top and bottom) and connector type (EV6/EV14/USCAR) before installation.
• ECU recalibration or tuning is required when upgrading from smaller OEM injectors to ensure accurate fueling at all load points.
• High impedance (12 ohm) - compatible with most factory and aftermarket ECUs without a resistor box or inline resistors.
• Adapters may be required for applications using shorter or longer fuel rail seats; verify injector length (64.1mm) against application before ordering.

Features

• 550cc/min (52 lb/hr) flow rate at 43.5 PSI provides substantial fuel delivery headroom for turbocharged, supercharged, and high-compression naturally aspirated builds.
• 6-hole multi-orifice disc tip produces a dual cone spray pattern for superior fuel atomization and combustion efficiency across modern multi-valve engines.
• High impedance (saturated) design at 12 ohms ensures direct compatibility with virtually all OEM and aftermarket ECUs without additional hardware.
• Rated for rail pressures up to 100 PSIG and maintains volume consistency to within 1% across the operating range for precise, stable tuning.
• Excellent low pulse width response down to 2ms enables clean idle behavior and smooth part-throttle drivability despite the high flow rating.
• E85 and ethanol compatible - suitable for flex fuel setups, race fuel applications, and standard pump gasoline.
• EV6/EV14 (USCAR) connector is universally used across domestic and import performance platforms, enabling broad ECU and harness compatibility.
• Factory O-rings installed on top and bottom - ready to install straight from the box.

Product Description

The Bosch 0280158117 is a genuine EV14 high-impedance fuel injector rated at 550cc/min (52 lb/hr) at 43.5 PSI - one of the most widely used high-flow injectors across both domestic and import performance builds. Its 6-hole multi-orifice disc tip produces a precise dual cone spray pattern that delivers finer fuel atomization than single-orifice designs, improving combustion efficiency, idle quality, and throttle response even at elevated flow rates. The 12-ohm high impedance design makes it directly compatible with virtually any factory or aftermarket ECU without resistor boxes or inline resistors.

Originally OEM on the Ford Mustang Shelby GT500 5.4L supercharged V8, the 0280158117 has found widespread use as a performance upgrade across turbocharged four-cylinders, forced induction V8 platforms, and flex fuel applications. Rated to 100 PSIG and compatible with gasoline, E85, and race fuels, it maintains consistent flow to within 1% across the pressure and temperature range. ECU recalibration is required when upgrading from smaller OEM injectors to ensure accurate air-to-fuel ratios at all operating conditions.
