First symptoms of that coil failing was a very slight hesitation under acceleration once the car warmed up. Not 20 km after I replaced that first failed coil I'm getting that slight hesitation again. Another coils was going to go. Now I know it's not a fluke. Ordered a new set from Pelican and installed them. It's all good now. One the bright side, it now takes me less than 2 hours to change the coils, I got better.

3 lessons learned from project:
1.) Get quality parts.
2.) Change plugs every 40K.
3.) Change coils at the same time. My car was kept very well (garage, no salt ever) and the coils were starting to crack up anyway.

The coils didn't fail. They were 1) damaged during installation, helped by their lack of quality; 2) band-aided with dielectric grease.

100km drive. Hot day. The band-aid melted. So to speak.

But really the odds are the coils would have failed anyway. That hard plastic would have come apart from the vibration and heat up cool down cycles in not many more miles.

So (1) above is where it belongs: at the top of the list.

That's harsh. You should read the thread again. The plastic mouth around the connector cracked. That just can't cause the coil to fail, especially since it has seen no water since the installation. But in short: yes, those coils were crap.
