Change Ignition coil w/spark plugs?

[Rtraveler]

My 2012 Sentra has 102k miles so I’m changing the spark plugs. I bought the NGK spark plugs and I also bought the intake manifold gasket since you have to remove the intake manifold to replace spark plugs. Should you replace the ignition coils too?

Personally I don't until an ignition coil fails. However it also depends on if you want to go through the process at a later date to change one of them if they do fail. Some people just don't want the hassle and will do all the items necessary while taking the intake manifold off once.

So in my opinion, it's a preference.
