Product Title
8-98259290-0 Injector Nozzle Assembly for Isuzu 6WG1 Engine

Product Overview
This injector nozzle assembly is specially designed for the Isuzu 6WG1 engine series, with part number 8-98259290-0. The injector nozzle is the terminal actuator of the fuel injection system, responsible for atomizing high-pressure fuel into fine particles and delivering them precisely into the combustion chamber – directly affecting engine power output, fuel efficiency, and emission levels. Featuring precision-mated plunger components and multi-orifice spray design, it ensures uniform atomization and moderate fuel penetration, fully meeting the high-power injection requirements of the 6WG1 engine.

Key Features

  • Precision mating – Needle and nozzle body are high-precision lapped as a matched set with controlled clearances for reliable high-pressure sealing and injection consistency.

  • Optimized spray pattern – Multi-orifice nozzle design with calibrated spray angle and penetration for fine, even atomization and complete combustion.

  • Premium material – Made of imported heat-resistant alloy steel, resistant to high-temperature corrosion under high injection pressures and combustion gas exposure.

  • OEM standard – Manufactured to Isuzu/DENSO technical specifications, fully interchangeable with original injectors.

  • 100% tested – Each unit undergoes injection quantity, spray pattern, and sealing performance testing before delivery.

Technical Specifications

  • Engine Model: Isuzu 6WG1

  • Part Number: 8-98259290-0

  • Type: Injector Nozzle Assembly

Installation & Usage Tips

  • The injector nozzle is a precision component – handle with care; avoid dropping, impact, or contamination of internal parts.

  • Professional installation with specialized tools is recommended; clean the injector mounting hole before installation.

  • After installation, use a diagnostic tool to rewrite or match the injector correction code (QR code / IMV code, depending on system type).

  • Periodically check injector return flow and injection quantity using professional equipment to ensure balanced operation across all cylinders.

Packaging & Delivery

  • Each unit comes in individual packaging with a sturdy carton box.

  • Adequate stock available; orders are shipped within 1–3 working days.
