What is the part number of the 1ZZ coil?
There isn’t a single universal part number for the 1ZZ ignition coil. The 1ZZ-FE engine uses four coil-on-plug ignition coils, and each coil has its own part number that can vary by year, market, and supplier. To identify the correct part, you need the vehicle’s VIN and engine details and should consult Toyota’s official catalogs or a dealership.
Understanding the 1ZZ-FE ignition system
The 1ZZ-FE engine, used in a range of Toyota models from the early 2000s onward, employs coil-on-plug (COP) ignition technology. Each cylinder has its own coil responsible for delivering the high voltage to the spark plug. Because coils can be updated or replaced with different revisions over time, the exact part number may differ even for the same engine code.
Why the part number matters
Using an incorrect coil can cause misfires, rough idle, reduced fuel economy, or drivability issues. An exact part number ensures compatibility with the ignition control system and proper spark characteristics.
How to find the exact coil part number for your vehicle
To locate the precise part number for a 1ZZ coil on your car, use these steps:
- Check the coil(s) for stamped part numbers or barcodes—the label may be on the coil body or boot.
- Gather your vehicle details: year, model, trim, VIN, and engine code (1ZZ-FE).
- Consult the official Toyota Parts Catalog or Toyota TechInfo (TIS) portal using the VIN to pull the exact coil part numbers for each cylinder.
- Contact a Toyota dealership or authorized parts retailer with your VIN to confirm compatibility and pricing.
- Consider OEM vs aftermarket coils; ensure any aftermarket option references the correct OEM part numbers for your VIN.
Conclusion: The 1ZZ coil uses four individual COP coils, and the exact part numbers depend on the vehicle’s year, market, and supplier. Verifying with the VIN and official catalogs is the reliable way to ensure you obtain the correct parts for all four cylinders.
Summary
There is no single universal part number for the 1ZZ coil. The correct coils are identified by VIN and engine specifications, and you should reference Toyota’s official catalogs or speak with a dealer to confirm the exact part numbers for all four COP coils. Replacing all four coils at once is often recommended to maintain optimum performance and reliability.

How to know which ignition coil to get?
The 3.0-ohm coil should be used on PerTronix Ignitors installed on four- and six-cylinder engines while 1.5-ohm coils should be used for eight-cylinder applications. These coils can be used on virtually any inductive (non-capacitive discharge) ignition system.
What is the part number of the ignition coil on a Toyota?
The Ignition Coil (#90919-02230), an essential Engine-Fuel part within the Glow Plug system, is instrumental in the ignition process.
Are ignition coils numbered?
Yes, ignition coils are numbered to correspond with the engine cylinders, though the numbers may be stamped directly on the coil or on the wiring harness that connects to it. This numbering is crucial for correct engine function, as misplacing a coil or its wire can cause misfires or rough idling.

How to find the numbers
- Look for markings: The numbers are often physically molded into the coil pack or its plastic housing at the base of the connector.
- Consult the service manual: If the numbers aren't obvious, the vehicle's service manual or an under-hood diagram will show the correct cylinder order for your specific make and model.
- Check the wire harness: For older systems, the numbering might be on the connectors of the high-tension leads rather than the coils themselves.
Why numbering is important
- Correct firing order: The numbers ensure that the coil fires at the correct time for each cylinder, which is essential for the engine's combustion cycle.
- Prevent misfires: If the coils or wires are mixed up, the engine will not run correctly and may exhibit symptoms like misfires or rough idling.
- Easier replacement: The numbering makes it easy to correctly install replacement coils and their corresponding wires.
