I needed a replacement starter for my mower and wasn’t completely sure which one would fit. I sent them a message and they got back to me quickly, asked for my model information, and helped confirm the right part before I ordered. Everything was handled professionally and the communication was great. Very happy with the service.

2-Piece Throttle Body Fuel Injector for Polaris
This package contains two throttle body fuel injectors for Polaris RZR XP 4 1000 2014-2023 vehicles and feeds fuel into the engine at the throttle body for controlled combustion. It is matched to OEM cross-reference 2521387 for fuel injector replacement service.
Overview
The 2-piece throttle body fuel injector for Polaris RZR XP 4 1000 2014-2023 supplies the precise fuel delivery needed after injector wear or clogged nozzles. It is intended for owners working on a Polaris RZR XP 4 1000 that idles rough, hesitates under throttle, or runs weak during extended off-road work. Replacing the old throttle body fuel injectors with this pair restores balanced injector output across the engine.
Built For Performance
- Two injectors in one set for matched replacement on a multi-cylinder Polaris RZR engine.
- Newly manufactured injectors with no prior fuel system residue.
- OEM cross-reference 2521387 for identification with the Polaris fuel system.
- Works as a throttle body injector set for the direct fuel delivery platform found on the RZR XP 4 1000.
Fits These Machines
- for Polaris RZR XP 4
On-The-Job Use
- Restoring fuel delivery after the original injectors have long service hours or known operating.
- Used in trail trips, dune use, and heavy-duty off-road driving where consistent fuel flow matters.
- Fuel system maintenance work on the idling RPM range and throttle area.
- Replacing a fuel injector set during engine top-end restoration.

Good To Know
Q: Does the 2521387 number cover a single injector or a pair? A: The 2521387 number is the OEM reference used for the injector component, and this listing includes a two-piece set so the engine can be serviced as a balanced match when installed.
Q: What else should be checked before installing these injectors? A: Clean the throttle body mounting surface and inspect the fuel rail O-rings for damage before install. Good nozzle seals will protect the fuel pressure and the injector angle for correct engine running.
Slight variation in finish or dimensions may occur between production runs, and the fit can depend on serial number, so confirm compatibility before ordering.
