What This Injector Does
The N14 Celect and Celect Plus fuel system runs a cam-actuated, electronically timed injector. The ECM commands the solenoid, the solenoid controls metering, and the rocker-driven plunger does the pumping. That means the injector is both a pump and a nozzle in one body. When it drifts, you feel it in fuel economy long before you get a code.
This is an aftermarket direct replacement built to the N14 flow specification, with a new nozzle and plunger assembly and new internal components. The mounting bore, hold-down, and electrical interface match the Celect and Celect Plus arrangement, so the injector drops into the same pocket and lands on the same wiring harness terminals as the unit you pull out.
Sold individually. There are six per engine. Most shops replace the full set rather than one hole, because a single new injector against five worn ones will show up as an imbalance on the fuel rate readings and can mask whatever was actually wrong.
Why These Numbers Cross
3411767 is the base number for this Celect injector. 3411385 is an earlier release of the same injector family carried forward on service parts lists, and it shares the plunger and nozzle spec, the body dimensions, and the solenoid interface, so the two are handled as one part in most catalogs.
3411767PX and 3411767RX are the same injector under reman and exchange suffix conventions. The base digits are identical because the hardware is identical. The suffix tells you how the unit was supplied, not what it fits. EX631767 follows the same pattern from an exchange program listing.
3083662 and 209982X show up as superseded and alternate references pointing at the same N14 Celect injector. They cross because the flow rate, spray pattern, and mounting geometry match. That is a starting point for identification, not a fitment promise. Read the number stamped on the injector body you pulled, and confirm the engine serial number before you order.
Before You Order
Confirm the engine is an N14 and whether it is Celect or Celect Plus. The two use different ECM calibrations and injector coding practices, so check the number on the old injector before assuming a match. Engine serial number is the reliable check. VIN alone will not always tell you what was installed after a repower or an in-frame.
Diagnose before parts. Cylinder cutout testing, injector resistance checks at the harness, and a look at fuel supply pressure will separate a bad injector from a bad wire, a plugged filter, or a worn cam follower. A dead hole with good electrical values is often a stuck plunger; a dead hole with an open circuit is usually the harness or the connector pin.
3411767 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 3411767. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Do I have to replace all six injectors at once?
You do not have to, but most shops do. Mixed wear across the set shows up as uneven fuel rates and can make the engine feel no better after the repair. If the engine has high mileage and you already have the valve cover off, doing the set saves a second teardown.
Is 3411385 the same injector as 3411767?
They cross to the same N14 Celect injector in most listings, sharing nozzle and plunger spec and the same mounting and electrical interface. Numbers are listed for identification only. Verify against the number stamped on the injector you removed and your engine serial number before ordering.
Does this injector need to be coded or calibrated to the ECM?
Celect and Celect Plus systems handle injector trim differently depending on the calibration loaded in the ECM. Check what your engine expects with a service tool before you button things up. Also set injector adjustment per the engine's overhead procedure after installation, or you will chase a miss that is not the injector's fault.
