Specs At A Glance

Good To Know

Q: Can I replace just one injector? A: Yes, a single failed injector can be replaced on its own, though many techs service the full set at once for even fueling. Always confirm the injector you remove matches the part number listed here.

Q: Do I need new seals or O-rings? A: Fresh seals are recommended any time an injector is removed and refitted to prevent leaks and vacuum issues. Inspect the connector and wiring harness while you have the fuel rail apart.

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