Generally speaking, coil packs last up to 5 years or 120,000 miles before they require replacement. Coil packs will last a long time but their continued exposure to heat and friction can naturally wear them down. The coil pack can also become damaged by carbon accumulation.
How do you test a Subaru WRX coil pack?
Open your hood and unplug all four wire pin connectors on the coil pack. Plug the multimeter leads into the left two outlets on the face of the coil pack. The resistance reading should be about 0.73 ohms, plus or minus 10%. Repeat with the right two outlets on the coil pack.
Average lifetime of ignition coil is around 100,000 miles or more. It is not an easy worn out replacement car part but still could fail for variety of reasons.

What kills ignition coils?
What kills ignition coils is location; being mounted in one of the hottest, most vibration prone and dirtiest parts of the engine. Modern ignition coils are typically located between two camshafts on the valve cover and exposed to dirt and oil.

What causes a coil pack to burn out?
Improper match between the electrical source and the coil rating is sometimes a cause for coil burn-out: Voltage Too High. The operating voltage should not be more than 10% higher than the coil voltage rating. Excessive voltage causes excessive coil current which overheats the coil.
Why is my coil burning after 1 day?
If the user vapes very regularly, the coil will quickly dry out in patches, or completely. When this occurs, it will often burn out. Many vapers unknowingly use the wrong e-liquid with the wrong type of device, leading to frustration when their coils keep burning without clear reason.
Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
