Also known as compact electrical transformers, ignition coils are a part of your Toyota's ignition system and connect either physically or sit atop the spark plug. They help convert the 12-volt current in car batteries to a higher voltage necessary to ignite the fuel and start the engine. While some ignition systems found in older vehicles use just one coil for all of the cylinders, newer models typically use one coil for each cylinder.

The following signs could be indicators of a faulty ignition coil:

• Poorer fuel efficiency than normal
• Illuminated "check engine" light possibly caused by faulty coils that trip the engine computer
• A hard-to-start vehicle, especially when one coil is used for all cylinders since a faulty coil would fail to provide the engine with any spark
• Rough idling and engine jerking
• Backfiring, which occurs when unspent fuel in the combustion cylinders leaves through the exhaust pipe

Here at BE FORWARD, we stock ignition coils for Coil-On-Plug (coils that sit on top of the spark plug) and Coil-Near-Plug (coils connected by wire) ignition systems for most Toyota models and years. Find yours in great condition and at a great price with us now!
