Gautory Fuel Injector & Harness Kit for Polaris Ranger/RZR 800 — 2 Sets, OEM-Compatible Corrosion-Resistant

Gautory fuel injector and harness kit replaces factory injectors for Polaris Ranger and RZR 800 models, restoring fuel delivery and improving engine response.

If your Polaris RZR or Ranger 800 is running unevenly, stalling, or showing reduced throttle response, faulty injectors or a worn harness can be the cause. This Gautory kit includes two complete sets of injectors with matching wiring harnesses engineered to fit a range of Polaris 800 vehicles from 2011–2017. Built to OEM-compatible specifications with corrosion-resistant materials, the kit aims to bring consistent atomization and reliable electrical connections back to your fuel system.

Will these injectors fit my Polaris model?

Compatibility covers many Polaris 800 models across model years. The kit fits RZR 800, RZR S 800, RZR 4 800, Ranger 6x6 800, Ranger Crew 800, Ranger 800, and Ranger XP 800 within the listed years. Always verify part numbers and year ranges before purchase.

• Supported years: 2011–2014 (RZR/Ranger variants), up to 2017 for certain Ranger 800 models
• Replaces part numbers: 0280158197, 1204318, 1204319, GX1111IJ117XG
• Check VIN and OEM part reference to confirm exact fit

How do these injectors affect performance and fuel economy?

Properly operating injectors deliver a consistent spray pattern and accurate flow rates, which helps the engine run smoother and use fuel more efficiently. These injectors are manufactured with precision flow control and uniform atomization to reduce uneven running and poor combustion.

• Precise flow improves combustion stability and throttle response
• Uniform atomization supports more complete fuel burn, potentially improving economy
• Quality materials minimize leaks and prolong service life

What materials and build quality can I expect?

The Gautory kit combines alloy metal and engineered composite plastics chosen for corrosion resistance and durability. Components are produced with experience from over ten years in injector manufacturing to meet or match OEM tolerances and electrical connections.

• Alloy metal bodies resist corrosion and wear
• Composite plastic fittings protect seals and wiring interfaces
• Harness connectors match factory pin layouts for plug-and-play replacement

How difficult is installation and what should I prepare?

Installation is straightforward for someone with basic mechanical skills and common tools, but it requires careful handling of fuel lines and electrical connectors. Follow safety precautions for depressurizing the fuel system and work in a well-ventilated area.

• Recommended: simple hand tools, safety gloves, and eye protection
• Depressurize fuel rail before removing injectors to avoid spills
• Verify all electrical connections are secure and routed clear of heat sources

Who is this for: This Gautory injector and harness kit is designed for off-road owners, mechanics, and fleet operators who maintain Polaris RZR and Ranger 800 models listed above and want a durable, OEM-compatible replacement. It's a good choice for anyone replacing aging injectors, repairing wiring faults, or restoring consistent engine performance without sourcing dealer-only parts.
