Specs At A Glance

Good To Know

Q: Is the injector compatible with stock fuel rails? A: Yes, it matches the factory rail mounting and O-ring size for direct installation.

Q: Should I replace all injectors at once? A: It is recommended to replace a faulty injector only, but if multiple are failing, a full set is wise.

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