My anecdotal experience,,, I've replaced lots of cracked old coil packs on all types of engines, once installed like above, never had one fail/crack again....

Maybe not fully seated squarely, then over tightened, maybe unevenly..?

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

"What happened here?" Maybe not fully seated squarely, then over tightened, maybe unevenly..? Or just age, take your pick. Or a combination of above. No matter the reason for failure, new ones should have a very very small amount of dielectric grease spread evenly(not too much..! ) on plug, then hand fitted till it seats fully, then gently tightened down evenly to just barely snug, not 20 ft lbs. Remember these are just plastic and can't take a lot of clamping force. The upgraded coil packs have a thicker/taller/beefier bolt hole bore. My anecdotal experience,,, I've replaced lots of cracked old coil packs on all types of engines, once installed like above, never had one fail/crack again.... jmo

Those are about what mine looked like after ~18 years and 60k miles. I think that's pretty normal?
