A: Installation should be performed by a qualified technician. Ensure the injector bore is clean and free of debris. Replace the copper washer and O-rings with new ones (not included). Torque the injector clamp to manufacturer specifications. After installation, bleed the fuel system and check for leaks before starting the engine.

Q3: How can I verify if my injector is failing and needs replacement?
A: Common symptoms of a failing injector include rough idling, black smoke from exhaust, decreased engine power, poor fuel economy, and hard starting.
