Question Coil replacements

Sorry this is double posted. So I've got a misfire issue caused by faulty plug/coil. Service records show that CYL 2 coil was replaced at 34,000 miles and CYL 1 was done at 77,000 miles. The Engine harness fix done at 90,000. My car is at 100,820 miles and now CYL 3 coil needs replaced along with the plug according to dealer($330). They also suggested I change the other 5 plugs (another $370) I always do plugs as sets, not individuals.

So, Here is my question...should I just replace all 6 coils as well when I do the plugs?? I can get a GREAT deal on a set of six AC DELCO online. I'm Hoping that replacing coils at same time as plugs I would eliminate any more issues with coils failing one at a time. Any extra input/advice from you all would really be appreciated.

THANKS!!

If you can get all of them at a price you like, then go for it! I don't see any reason not to.

Re: Coil replacements

When I replace the coils should I put some dielectric grease inside of just the boot or Should I also put some on the connectors for the coil packs as well?
