What to quote
State the fuel injector quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Sentra · Engine, Fuel, Cooling, Electrical & A/C
For Sentra fuel injector, start with port or direct-injection engine; use injector label and rail interface and nozzle, connector and seal set to separate similar variants.

| Record | Details to retain |
|---|---|
| Port or direct-injection engine | Identify port or direct-injection engine from the vehicle, installed assembly or readable label. |
| Injector label and rail interface | Show injector label and rail interface in photographs and retain measurements that distinguish the interfaces. |
| Nozzle, connector and seal set | Specify nozzle, connector and seal set together with every piece required in the quoted assembly. |
Port, direct and turbo injection systems need separate rail, nozzle and calibration checks.
For this fuel injector, keep chassis, production date, engine, transmission and sales market on the same record. The Sentra B13–B18 identification guide explains why a regional name alone is insufficient.
When this component is part of a mixed system order, use the fuel, cooling, electrical and a/c to separate neighboring assemblies.
Send overall and mounting or connection photographs. For the fuel injector, retain injector label and rail interface and nozzle, connector and seal set; mark unknown values instead of borrowing a number from another generation. Use the OE and vehicle-identification checklist to organize the evidence.
Give every linked assembly its own specification; approving the fuel injector does not confirm the surrounding parts.
Sentra High-Pressure Fuel Pump — Use only for a proven direct-injection application; B17 1.8 port injection does not inherit a B18 DIG pump. Confirm b18 2.0 DIG or other proven direct injection and cam drive and mounting flange on its own order line.
Sentra Spark Plugs — Naturally aspirated and 1.6 turbo engines can require different plug specifications; matching thread size alone is unsafe. Confirm petrol engine and induction type and thread, reach and heat specification on its own order line.
Sentra EGR Valve — EGR equipment changes by engine, emissions market and production date; physical fit does not establish emissions compliance. Confirm engine and emission-system revision and valve, cooler and pipe relationship on its own order line.
State the fuel injector quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Cap inlet and nozzle individually and retain identification labels.
Before approving the fuel injector, agree sample and inspection requirements using the quality-control checklist. Return to the Sentra parts directory for other systems.
