ignition coils - seller claims crack is due shipping
i know it was stupid buying used set of ignition coils but at that time it was the only option, so bear with me on this.
now, i explicitly asked seller if any cracks, he said no! perfect condition!
now i received this:
seller claims he sent good items, this is shipping problems.
personally that kind of crack is the one i have on my car and it’s a known cayenne issue and that means the seller being dishonest or am i being biased here?
Also, the final digits in the part number on there are .02, which are OLD! I believe they keep tweaking things, hopefully improving, and are now up into the 20's on that number.
The coils are not worth the risk of installing them. The previous owner (maybe not the eBay seller) probably took them out while troubleshooting something, and thinks they are still worth using. I believe coils and misfires are one of the few things on a car where marginal performance should be a common concern. I.e., the coil might work just fine, but barely, making a spark to cause combustion, and then something changes and they drop just a little, so under certain conditions you don't get combustion. Next thing you know, you've got a bore-scored block.
Leave negative feedback immediately and return them as "not as described" so you shouldn't have to pay return shipping.
I won't repeat the scolding regarding buying used coils.
That's where they crack from use when they need to be replaced. I wouldn't spend the time to install any of those unless you're just keeping 1 or 2 in the car as spares in case you have a failure on a trip.
I have one spare coil and for fun put some heat shrink over the barrel of the coil where they crack as a preventative measure. I may do this to all my coils when I do spark plugs at 35K or so. Maybe it won't help but meh, worth a try.

That's actually a great idea. I'm going to do the same with the new set I have before I install them.

The plastic may still crack, but if there is an insulating material covering it, it will prevent water ingress through the crack and any arcing, so may very well prolong the life of the coils.
