What is the part number of the ignition coil on a 2014 Toyota Corolla?
The ignition system on a 2014 Toyota Corolla uses four coil-on-plug ignition coils, one per cylinder. There isn’t a single universal part number for all cars; the exact coil part number depends on the supplier, region, and production batch, so you’ll need to confirm it for your specific vehicle.
What you should know about coil part numbers
In the 2014 Corolla with the 1.8-liter engine, ignition coils are individual coil-on-plug units rather than a single “coil pack.” That means there are four coils, and each must match the exact part specification for your car. OEM (Toyota) and OEM-supplier coils (such as Denso) can share the same model number across all four cylinders on a given vehicle, but variations can occur by market and production run. Always verify against your VIN and the official parts catalog before purchasing.
VIN-based lookups and official catalogs
The most reliable way to identify the correct coil part number is to use VIN-based lookups and official catalogs. These resources account for regional part differences and any production revisions.
- Enter your vehicle’s VIN on Toyota’s official parts website or at a Toyota dealership to retrieve the approved coil part number for your car.
- Inspect the current coils for any stamped numbers or codes that indicate the coil model or compatibility.
- Cross-reference chosen coils with the supplier’s catalog (Toyota, Denso, or trusted aftermarket) to ensure compatibility with the 1.8L engine.
- Consult the service manual or a trusted parts diagram to confirm whether all four coils share the same part number for your configuration.
Using VIN-based catalog lookup is the most reliable method to guarantee you get the correct ignition coil part number for your Corolla.
Practical considerations when replacing ignition coils
When planning a replacement, consider whether to replace all four coils at once and whether you should pair the job with spark plugs and boots for a complete ignition system refresh.
- OEM vs aftermarket: OEM coils (Toyota/Denso) offer the best compatibility and warranty, while reputable aftermarket options can be cost-effective if you verify compatibility.
- Replace all four coils at once: Replacing all four coils is common if one has failed, to reduce the risk of future misfires from aging coils.
- Check related components: Worn spark plugs or damaged boots can cause misfires; consider replacing them in tandem with new coils for best results.
- Warranty and fit: Ensure the coil set includes a warranty and that the return policy supports correct fit if a part is not right for your VIN.
Careful planning and using VIN-verified parts can help prevent mismatches and ensure a smoother repair.
Summary
For a 2014 Toyota Corolla, ignition coils are four separate coil-on-plug units—one per cylinder. There is no single universal part number; the exact coil part number depends on the supplier, region, and production batch. To obtain the correct number, verify via your VIN with official Toyota catalogs, inspect the existing coils for markings, and consult a dealership or reputable parts retailer. If you’re addressing ignition issues, replacing all four coils (often with new boots and spark plugs) is a common and prudent approach.

How do I know which ignition coil to buy?
To find the correct ignition coil, start by checking your vehicle's manual or using its VIN to find the specific part number. You also need to determine the type of ignition system your car uses (e.g., coil-on-plug, distributor-based, or DIS) to ensure you get the right style and design of coil. Finally, ensure the new coil matches the original specifications for resistance and voltage to prevent misfires and other engine issues.
Determine your vehicle's needs
- Use the VIN or vehicle manual: The most accurate way to find the right coil is to use your vehicle's VIN or consult the owner's manual to find the OEM (Original Equipment Manufacturer) part number.
- Identify the ignition system type: Your car's system dictates the coil style. Common types include:
- Coil-on-plug (COP): A coil sits directly on top of each spark plug.
- Distributor-based: A single coil sends power to spark plug wires via a distributor.
- Distributorless Ignition System (DIS): Uses one or more coils to power multiple spark plugs, but without a distributor.
- Note key specifications: Pay close attention to the primary and secondary resistance, voltage ratings, and turns ratio, as these must be compatible with your vehicle's system.

Choose a quality coil
- Match the brand: It's best to use coils from the same brand, or to replace all coils at once with matching parts to avoid performance issues caused by slight variations in specifications, FCP Euro says.
- Consider OEM vs. aftermarket: OEM coils are designed specifically for your vehicle, but some high-quality aftermarket brands can also be a reliable option.
- Check user reviews: Look for user reviews to gauge the real-world performance and durability of aftermarket coils.
