DeatschWerks 1000cc Fuel Injectors for B/D/F/H Series

DeatschWerks 1000cc Fuel Injectors - B/D/F/H Series (Honda/Acura)

These are a matched set of four DeatschWerks 1000cc injectors sized for the older Honda and Acura four-cylinders, covering the B, D, F, and H series engines. Once you're running boost or switching to E85, the factory injectors run out of fuel at the top of the map, and a bigger injector is the only way to keep the engine fed. At 1000cc/min these cover serious power on pump gas and give you the headroom E85 needs, and they're built to drop into the OEM-style injector location without surprises.

What "F Series" Means Here

The F-series fitment is the F22 and F23 engines found in the Accord and Prelude, not the F20C or F22C in the S2000. Those S2000 engines use a different injector setup entirely and are not what these are for. If you're shopping for an S2000, these aren't your part. If you've got an F22 or F23 Accord, you're in the right place.

High Impedance, OEM ECU Compatible

These use high-impedance coils, so electrically they match what the factory Honda ECU expects and clip into an OEM-style setup as a drop-in. That's the part that makes them easy to live with compared to a low-impedance injector that needs a resistor box or a driver. What high impedance does not do is let a 1000cc injector run right on a stock tune, which brings us to the next point.

You Still Need A Tune

Don't let "OEM ECU compatible" fool you into thinking these are plug-and-play. A 1000cc injector flows far more fuel than a stock calibration is expecting, so on a factory tune the car will run rich, run badly, or not start. You need a reflashable or standalone ECU and a tuner who can scale the injector data and dial in the fuel. Plan on tuning these as part of the install, because that's the only way an injector this size behaves at idle and delivers properly up top. DeatschWerks publishes injector data and offers tuning support, so the numbers your tuner needs are available.

Matched Set With A Flow Report

All four injectors are flow-tested and matched to within 1-2 percent of each other, and the flow report comes in the box. That matching is what keeps all four cylinders getting the same amount of fuel instead of one running rich and another lean, and it's the difference between a set that tunes cleanly with a smooth idle and one that fights you. Keep the flow report with your build records so your tuner has the exact numbers.

Built For E85 And Boost

E85 needs roughly 30 percent more fuel volume than gasoline to make the same power, which is why guys switching to ethanol usually need bigger injectors even if their power goal hasn't changed. The 1000cc rating gives you room for a high-horsepower E85 build or a strong boosted pump-gas setup without maxing the injectors out. They handle the aggressive fuels these builds tend to run, so you're not chasing injector problems every time you change your fuel.

Works With OBD1 And OBD2

These are set up to work with both OBD1 and OBD2 injector connectors, so you're covered whether you're running an early OBD0/OBD1 car or a later OBD2 setup. No cutting into your harness and no hunting for a plug that fits. Clip them in and move on to tuning.

One Note On Returns

Once injectors have been installed they can't be returned, so these are exchange-only. Confirm your sizing and your engine before you install them, and reach out before ordering if you're unsure whether 1000cc is right for your build.

These are for the B, D, F, or H series builder going E85 or chasing boosted power who has the tuning sorted to support a 1000cc injector. A flow-matched set of four with a real flow report, high-impedance coils that drop into an OEM-style setup, and the fueling headroom a serious build needs. They work with both OBD1 and OBD2, so get them clipped in, get it tuned properly, and they'll keep your engine fed everywhere it counts.
