Subaru Legacy and Coil Packs
Yes, the Subaru Legacy does have coil packs. Ignition coil packs are an essential part of the Legacy’s ignition system, responsible for providing the necessary spark to ignite the fuel and air in the engine’s combustion chamber. When a coil pack fails, it can lead to misfires and other ignition-related issues. It’s important to replace worn or damaged ignition coil packs to ensure the proper functioning of the vehicle’s ignition system.

What does a bad coil pack sound like?
If you hear spluttering and coughing sounds when you start the engine, an ignition coil is causing the problem. The sounds come from a cylinder that is not firing at all during the ignition process.

5 Symptoms of a Faulty Ignition Coil
- Misfiring Engine. An engine misfire makes the car feel shuddery and as though it’s out of rhythm.
- Engine Backfires. An engine backfire sounds like a bang or sharp cough, and it happens when unburnt fuel ignites in the exhaust system.
- Less Fuel Efficiency.
- Check Engine Light.
- Hard Starts.
What causes a misfire in a Subaru Legacy?
A misfire means that your engine isn’t running as efficiently as it should be: either there’s too much or too little fuel being injected into each cylinder, air is going into the wrong cylinders, or something is blocking the flow of exhaust gases out of the engine.
How long do Subaru ignition coils last?
60,000 to 100,000 miles
As a rule of thumb, you should replace your ignition coils anywhere from 60,000 to 100,000 miles after installation.
Do Subarus have ignition coils?
Being attuned to your Subaru’s sounds and movements will keep your vehicle performing as you expect for years to come, and one of the critical components demanding your attention is the ignition coil. This small device is the heart of your Subaru’s ignition system, supplying power to the spark plugs.
Do all vehicles have coil packs?
All automotive ignition systems (except diesels) have to generate a spark strong enough to jump across the spark plug’s gap. This is accomplished using an ignition coil consisting of two coils of wire wrapped around an iron core.
Why do Subarus sound like they are misfiring?
The 2.5-liter Subaru engine makes use of something called unequal length headers, which are exactly what they sound like. The header piping from cylinders one and three are of a different length than those from two and four.
How do I know if my Subaru has a misfire?
You can identify a misfire by looking at the engine temperature gauge and listening for an irregular idle or engine noise. A faulty spark plug or ignition coil could be the cause of this and should be checked for damage before removing them from the car engine.
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.
Should I replace all ignition coils or just the bad one?
Replacing one coil might cure the misfire and codes for now, but the other coils could fall prey to the same failure and codes. Replacing all for the coils at a time will save a comeback. This is why some ignition coil manufacturers package coils in sets.
