A single coil pack runs $100 to $400 installed. Replacing the full set on a V6 or V8 runs $300 to $900. Many modern engines have a coil-on-plug (COP) for each cylinder - "coil pack" and "ignition coil" mean the same thing on these.
Most drivers pay $150 to $250 for a single coil pack replaced at an independent shop.
One bad coil vs full set replacement.
OEM coils last longer but cost 40-80% more.
V6/V8 rear coils on transverse engines need intake removal.
Often replaced at the same time, $30-$200 in parts.
Older waste-spark coil packs cost less per unit.
Dealerships charge 40-60% more for OEM coils.

On a high-mileage engine (100K+), yes. On a low-mileage engine, replacing only the failed coil is acceptable - just keep an eye out for others.
Typically 80,000-150,000 miles. Heat, vibration, and worn spark plugs shorten their life.
Yes - prolonged misfires dump raw fuel into the catalytic converter, destroying it. Fix misfires promptly.
A scan tool shows the cylinder number (P0301 = cylinder 1, P0302 = cylinder 2, etc.). Swap that coil with another to confirm the code follows the coil.
Quality brands (Denso, NGK, Bosch, Delphi) are fine. Cheap no-name eBay coils have a high early-failure rate.
If they are over 60,000 miles old, yes. Worn plugs cause the coil to work harder and fail again sooner.
