Fitment & Installation Checks

Match year, model and exact 3.3L V6 engine.
Compare connector keying, coil body, mounting point, boot profile and printed reference numbers.
Confirm spark plug reference 4504 for the exact engine.
Follow the vehicle manufacturer's spark plug gap and torque specification; do not guess.
Inspect wiring, connectors and plug wells for damage, oil or moisture before installation.

Diagnostic note: A DTC or misfire code alone does not prove an ignition coil is faulty. If a misfire remains, continue diagnosis of wiring, injectors, fuel delivery, intake or vacuum leaks, sensors, compression and mechanical timing as applicable.

Q: Will the UF506 and 4504 kit fit my Toyota?
A: Confirm the listed year, exact 3.3L V6 engine, connector and reference numbers before ordering.

Q: What is included in this kit?
A: The package includes 6 ignition coils and 6 spark plugs.

Q: Which Toyota applications are listed?
A: Listed applications are Camry 2005-2006, Sienna 2004-2006 and Solara 2004-2008 with the listed 3.3L V6.

Q: Which ignition coil references should I compare?
A: Compare UF506, 90919-19025 and the other listed interchange references where applicable.

Q: Which spark plug reference is included?
A: The listed spark plug reference is 4504.

Q: Does a misfire code prove the ignition coil is bad?
A: No. Wiring, injectors, fuel delivery, air leaks, sensors, compression or mechanical issues can also cause a misfire.

Q: Should all six coils and plugs be replaced together?
A: That depends on diagnosis, age, mileage and component condition. A complete V6 set can be practical when the service plan supports it.

Q: Do I need to verify spark plug gap and torque?
A: Yes. Follow the exact Toyota engine service specification.

Q: What should I compare before ordering?
A: Compare year, engine, connector keying, coil body, mounting point, boot profile and printed references.

Q: What should be checked during installation?
A: Inspect wiring, connectors and plug wells for damage, oil or moisture and make sure each coil is fully seated.

Q: What if the engine still misfires after service?
A: Continue diagnosis of wiring, injectors, fuel delivery, intake leaks, sensors, compression and mechanical timing as applicable.
