Bosch EV1 42lb/440CC Fuel Injectors, 0280155968

The Bosch 0280155968 is a 440 cc/min fuel injector with an EV1 connector style, delivering the increased fuel-flow performance that builds require when stock injectors max out. Bosch fuel injectors lead the industry with robust design and superior performance, providing the headroom needed to support modified engines and forced induction setups.

Engineered for Modified Engines and Performance Builds

Engineered for Modified Engines and Performance Builds

A 440cc per minute flow rate at 43.5 PSI translates to roughly 42 pounds per hour of fuel delivery, making the 0280155968 the right size for moderately modified naturally aspirated engines and entry-level boosted builds. When stock injectors approach their maximum duty cycle, this injector restores fueling headroom without sacrificing idle quality.

Bosch OE Quality and Industry-Leading Reliability

Bosch OE Quality and Industry-Leading Reliability

All Bosch fuel injectors released to the aftermarket are produced to OE specifications, making them the perfect replacement for faulty fuel injectors. The same engineering trusted by automakers carries over into the aftermarket lineup, delivering reliable atomization, precise metering, and the long-term durability serious performance builds require to run consistently across the RPM band.

EV1 Connector Style for Wide Platform Compatibility

EV1 Connector Style for Wide Platform Compatibility

The 0280155968 uses the EV1 connector style, the original Bosch fuel injector connector found across many domestic and import performance platforms. EV1 compatibility makes this injector a popular choice for older LS engines, classic muscle car EFI conversions, and any application using EV1 wiring without the need for adapter harnesses or pin extraction work.

A Proven 440cc Bosch Injector for Performance and E85 Conversions

Stepping up boost, adding cams, or converting to E85 all increase fuel demand beyond what stock injectors can supply. The Bosch 0280155968 delivers consistent atomization and accurate metering at the flow rate these builds require, which is why this injector remains a popular upgrade choice for tuners working with EV1-equipped platforms.

Compatible With All Known Fuels Including E85

Compatible With All Known Fuels Including E85

The 0280155968 is rated for all known fuels, including pump gasoline, race fuel, and full E85. Flex fuel tunes constantly shift in chemistry, and these injectors are engineered to handle that variation without breakdown. Internal materials resist the corrosive effects of ethanol, making them a strong fit for dedicated E85 setups.

Precise Specifications for Accurate Tuning

Precise Specifications for Accurate Tuning

Each injector features a 14.5mm O-ring diameter on top and bottom, 74mm overall length, 12 ohm impedance, and a 100 PSIG maximum pressure rating. Accurate published specifications are critical for proper tuning, allowing tuners to input dialed-in injector data into the ECU for precise fueling at idle, cruise, and full load operation.

Backed by Bosch Warranty Coverage

Backed by Bosch Warranty Coverage

Every Bosch fuel injector is backed by Bosch warranty coverage against defects in materials and workmanship under normal conditions of use. Quantum Fuel Systems is American-owned and based in Ventura, California, offering US-based technical support to assist with sizing, fitment, and tuning questions for builds upgrading to higher flow injectors.

Frequently Asked Questions

The Bosch 0280155968 atomizes and meters fuel into the engine's intake stream at precise volumes determined by the ECU. Rated at 440cc per minute (42 pounds per hour) at 43.5 PSI, it supplies the increased fuel flow required by modified engines, making more power than stock injectors can safely deliver under load.

EV1 connectors are common across many domestic and import performance platforms, including older LS series engines, classic Ford 5.0L Mustangs, GM TPI applications, early DSM 4G63 turbo engines, and many other EFI conversion projects. The 0280155968 is a strong fit for these platforms without requiring adapter harnesses or pin extraction.

Yes. The 0280155968 is compatible with all known fuels, including E85 and other ethanol-based blends. Internal materials are engineered to resist the corrosive effects of ethanol, allowing these injectors to perform reliably in flex fuel applications and dedicated E85 setups without breakdown of seals or internal components over time.

Injector sizing depends on horsepower target, brake-specific fuel consumption, and fuel type. As a rough guide, 440cc injectors typically support up to 400 horsepower naturally aspirated on gasoline or roughly 280 to 300 horsepower on E85. Always consult a qualified tuner to confirm sizing matches the specific build's power goals.

Yes. Larger injectors deliver more fuel per pulse than the OEM units, so the ECU must be re-tuned to account for the new flow rate. Without proper tuning, the engine will run rich, foul plugs, and may not start correctly. Always work with a qualified tuner when stepping up to higher flow injectors.
