This is a set of four high-performance fuel injectors, crucial for the precise delivery of atomized diesel fuel into the combustion chambers. Engineered to exact specifications, they ensure optimal fuel atomization and spray patterns for efficient combustion and maximum power output. A worn or faulty injector can result in poor fuel economy, rough idling, increased emissions, and potential engine misfires.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first noticeable symptom of failing fuel injectors is often an uneven idle or a slight loss of engine power. If left unaddressed, fuel delivery can become inconsistent, leading to misfires, increased exhaust emissions, and a significant drop in fuel efficiency. Prolonged operation with faulty injectors can cause unburned fuel to wash oil from cylinder walls, potentially leading to internal engine damage.

Installation Tip

Always use new copper sealing washers for the fuel lines and ensure they are torqued to the manufacturer's specifications to prevent leaks. Do not reuse old seals or O-rings.

Service Note

Inspect the fuel filter, fuel lines, and the fuel pump for any signs of contamination or wear when replacing the fuel injectors.
