How long do Subaru ignition coils last?

How Long Do Subaru Ignition Coils Last?
Subaru ignition coils are designed to last for a significant period of time. According to the information available, on average, ignition coils last for up to 100,000 miles depending on the engine type, vehicle type, and vehicle maintenance. This component does not fail easily, and when something goes wrong with them, it’s usually caused by another part, like the spark plug or fuel injector malfunctioning.
It’s important to note that the lifespan of ignition coils can be affected by various factors such as wear and tear, heat, moisture, and the overall condition of the vehicle. Ignition coils are durable components, but they are not indestructible and are not designed to last forever.
If you experience symptoms such as rough driving, a flashing check engine light, or engine struggling to start, it could be an indication of a failing ignition coil. In such cases, it’s advisable to have the ignition coils inspected and replaced if necessary.
In summary, while Subaru ignition coils are designed to last for a considerable mileage, their lifespan can be influenced by various factors, and it’s important to monitor their condition and address any issues promptly to ensure the proper functioning of the vehicle.

Can ignition coils fail intermittently?

Yes. An ignition coil can cut out intermittently, usually under a load but not always.

Should I replace spark plugs and ignition coils at the same time?

Yes, it is possible to replace an ignition coil without changing the spark plugs. Ignition coils are responsible for generating the high voltage needed to ignite the fuel and air mixture in the engine’s combustion chamber, while spark plugs provide the spark that ignites the mixture.

What is the life expectancy of an ignition coil?

around 100,000 to 150,000 miles
The lifespan of an ignition coil in a car can vary widely depending on several factors, including the quality of the coil, the driving conditions, maintenance practices, and the make and model of the vehicle. On average, an ignition coil might last around 100,000 to 150,000 miles (160,000 to 240,000 kilometers).

How often should ignition coils be replaced?

The ignition coil on car is supposed to last around 100,000 miles or more. You will have reduced gas mileage when coil begins to go bad and becomes less able to transfer power. Your car requires more fuel to run, this means you will spend more money on gas than normal.

Can ignition coils last 200k miles?

Ignition coils have a finite lifespan, typically around 100,000 to 150,000 miles. However, this can vary based on driving conditions and maintenance.

Should you replace all 4 ignition coils at once?

Coil packs are reliable and likely to last the lifetime of a vehicle. If anyone goes bad, there is no need to change all of them. However, if one pack starts malfunctioning after the odometer has around 75,000 miles, you should replace them all.

How do I know if my Subaru coil pack is bad?

Find the spark plug wire terminals and then plug your multimeter in two of them. Make sure that both terminals are pointing directly opposite of each other. The reading should be about 12,800 ohms, plus or minus 15%. If the reading is off, then the coil pack is bad and it needs to be replaced.

How much does it cost to replace ignition coils on a Subaru?

It can cost anywhere between $80 and $300 to replace an ignition coil. The exact cost depends on several factors, including: Your Subaru model.

Do ignition coils just go bad?

If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils. Nevertheless, on most vehicles can go 80,000 to 100,000 miles before requiring an ignition coil replacement.
