When changing ignition coil. Do you have to change all the ignition coil at once?

If one fails the other is usually not far behind it.

Changing Ignition Coil

i'd just replace one.

to protect them, good spark plug cables are needed. any excessive resistance in those, and that will cook a coil. and that's what i usually do. change plug leads when replacing a coil. *coil atop plug* configs don't require that.

kind of an opinionated Q. well the answers are. mine is anyway.

respect,

i've seen coils live forever. pulled 'em outta the mud at wrecking yards. still good. but i've had 'em go bad.

never once have i changed all coils on a given platform simply because another one went bad. and the good one(s) that weren't changed, live on.

i guess it's a good part. i couldn't find the manufacturers name for that product. so... and i cannot verify the app. but if that's the vehicle you have, then it's the right part. quality, have no idea.

old fart. racing and wrenching a long time.

FYI,

the notation says there are two on a vehicle. not that you have to buy two of 'em. they are not joined at the hip. can be replaced individually.

Those coils are both the same age. Yes, if your in a bind you can change one, but know the other one is not far behind it.

Most people, if they can will replace both. That way your done with it and don't have to go back in replace the other one latter. Save yourself some time and grief.
