Ignition
Your Subaru lets electric currents reach the engine through its ignition coil. This car part turns your battery’s low voltage into the thousands of volts needed to produce a spark in your spark plug, igniting your fuel. If you’re in need of 100% car parts, shop at SubaruOnlineParts for genuine equipment and accessories for select Subaru models and model years.

Get Maximum Engine Power with a Genuine Spark Coil
Subaru injection coils typically include an iron core, coils, and terminals. These components work together to receive, convert, and pass electric currents from your battery to the spark plug. Ignition coils are made up of primary and secondary coils. The primary one creates a magnetic field that collapses. In turn, it produces a high-voltage pulse in its secondary counterpart. Newer ignition systems, on the other hand, provide pulses through a power transistor.
Modern ignition systems often use coil-on-plugs or coil packs. The former sits above your spark plugs. Both systems allot one coil to each engine’s cylinder or pair of cylinders. Coil packs consist of multiple plug shafts attached to a rail and don’t require multiple connection cables. Single plug shafts, on the other hand, depend on high-voltage connectors for operation.

Failing to maintain parts of your ignition can give rise to serious car issues. Those that generate a higher voltage will wear out faster than those connected to wires with normal resistance. Your vehicle’s spark coils can also fail if they’re exposed to excess moisture, as this could result in serious engine problems. In some cases, you might even experience engine misfires, poor acceleration, or reduced gas mileage.
If you experience any of these issues with your engine, it might be time for a replacement. Shop at SubaruOnlineParts for 100% authentic parts and accessories. Our OEM engine components fit select Subaru models and model years, including the Ascent and XV Crosstrek. Browse our inventory to shop for genuine Subaru parts.
What are the different parts of ignition for a car?
Your ignition system comprises various components that play a vital role in its functioning. For example, the battery acts as a power source, and the breaker point or switch controls its flow. The ignition coil is responsible for transforming this electrical energy into high voltage and emitting a pulse to the spark plug, allowing you to start your car.
What are common ignition issues?
Having a faulty ignition system can cause decreased gas mileage, flickering dashboard lights, and a quiet starter motor. You can expect other issues like stalling, hard starts, or total engine failure if your ignition system starts to fail and become inconsistent.
Can a faulty car ignition switch drain my vehicle’s battery?
The ignition switch opens and closes the circuits, allowing electricity to flow within your vehicle. A faulty ignition switch prompts drivers to turn their key repeatedly to power their vehicle. Doing so drains your battery quicker or completely kills it. This can also lead to other electrical problems and mess up your car radio, wipers, and lights.
What are the different types of ignition systems?
There are four ignition system types: breaker-point, high-energy, waste spark, and direct systems. A break-point is the oldest type and has a lot of movable parts. High-energy systems use a switch that controls current generation for ignition. The waste spark ignition foregoes the conventional distributor for solid-state switches that are much more durable. Lastly, the coil-on-plug places a coil directly on top of each plug, hence its name.
How often should I replace ignition coils?
Car ignition coils are built to last around 100,000 miles or more, and they should only be replaced when your engine misfires or you notice cracks on its plastic or epoxy. If your car starts to consume more fuel, it can also be an indicator that you already need to replace your ignition coils.
