Keep fuel metering crisp and cylinders firing with the Beck/Arnley Fuel Injector 159-1101, a direct-fit replacement for the 1996-1997 Nissan Pickup, 1998-2004 Nissan Frontier, and 2000-2004 Nissan Xterra. A fuel injector delivers a precisely metered, atomized spray of fuel on command from the engine's control system, so a worn or clogged unit can show up as rough idle, misfire, hard starting, hesitation, or poor fuel economy. If a failed injector is the cause of those symptoms, this Beck/Arnley unit replaces it.
- Fuel injector: delivers metered, atomized fuel into the intake for the affected cylinder.
- Direct-fit application: installs on the listed Nissan applications as a straightforward replacement.
- Diagnose first: confirm the injector is the cause before replacing, since these symptoms can have other sources.
Injectors are commonly serviced as a matched set, so consider the condition of the others on the engine when servicing.
