DeatschWerks 1000cc Fuel Injectors for F/K Series

DeatschWerks 1000cc Fuel Injectors - K-Series (USCAR)

These are a matched set of four DeatschWerks 1000cc injectors built on the Bosch EV14 platform, sized for K-series builds that have outgrown their factory injectors. Once you're running real boost or switching to E85, the stock injectors simply run out of fuel, and a bigger injector is the only way to keep the engine fed at the top of the map. At 1000cc/min these cover serious power on pump gas and give you the headroom E85 demands, with a USCAR connector that plugs straight into most K-series setups running an aftermarket engine harness.

Read This First: You Need A Tune

These will not run on your stock ECU. A 1000cc injector flows far more fuel than the factory computer is expecting, and dropping them in without a tune will make the car run badly or not start at all. You need a standalone or reflashable ECU and a tuner who can scale the injector data and dial in the fuel. If you're not already set up to tune, sort that out before you buy these, because an injector this size is a tuning part first and a bolt-on second. Matched to the right ECU and a proper tune, they idle clean and deliver fuel accurately across the whole range.

Why Bosch EV14 And A Matched Set

The EV14 is the injector platform most of the industry has moved to because it atomizes fuel well, idles smoothly even at high flow rates, and holds up to aggressive fuels. DeatschWerks flow-tests and matches every set to within 1-2 percent of each other and includes the flow report in the box, so all four cylinders get the same amount of fuel instead of one running rich and another running lean. That matching is what lets a big injector still behave at idle and cruise, and it's the difference between a set that tunes easily and one that fights you the whole way.

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 almost always 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. The EV14 internals are compatible with E85 and the oxygenated race fuels these builds tend to run, so you're not chasing injector problems every time you change your fuel.

Check Your Connector

These come with the USCAR (EV6) connector, which is what most K-series engine harnesses built for modern injectors use. Factory Honda K-series injectors use a different plug, so if you're running an OEM-style harness you'll need the correct adapters to clip these in. We stock a K-Series Fuel Injector Adapter Harness that handles the common connector conversions cleanly, so confirm what your harness uses before you order and grab the adapters if you need them.

One Note On Returns

Once injectors have been installed they can't be returned, so these are exchange-only if there's ever an issue. Confirm your sizing and your connector before you install them, and keep the flow report with your build records.

These are for the K-series builder going E85 or chasing boosted power who already has the ECU and tuning sorted to support a 1000cc injector. A flow-matched set of four on the proven Bosch EV14 platform, with the fueling headroom a serious build needs and none of the drama a mismatched set gives you. Get the right connector adapters for your harness, get it tuned properly, and these will keep your engine fed everywhere it counts.
