Specs At A Glance

Good To Know

Q: Does this injector need any tuning after installation? A: No, it is a direct replacement for the OEM part and works with the factory ECU calibration. Reset any fault codes after installing and test-run the engine.

Q: Can I replace just one injector? A: Yes, this injector is sold individually so you can replace only the faulty unit. If the others show similar wear or age, replacing them together is often more efficient.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
