Can I change only one ignition coil on a Mazda?
Yes, if only one of the ignition coils has failed, you can replace only one. Most mechanics and dealerships don’t recommend replacing only one coil for several reasons. If one failed, another one might fail soon. Also, to avoid any performance issues, it is recommended to change all four. If you are on a tight budget, at a minimum, replace the one bad coil.
How often should I change the ignition coil on a Mazda?
It is not necessary to change ignition coils on a Mazda unless at least one of them fails. Ignition coils can last up to 200,000 miles. In a few cases, we have seen ignition coils fail as early as 60,000 miles.
