Changed my plugs and coil packs before a road trip last August and i can tell you that before and after is very very noticeable.
Leading evidence: 'Replace plugs and coil packs' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace both, they think the coils made the difference too' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I don't guess they've ever been changed so after 12 years and almost 90k I guess it's time...

However since most people change both, they think the coils made the difference too.

Just curious, as the passenger's side were in good shape during my last spark plug change, I had to buy 3 new ones for the driver side......just like ur pictures or worse.....

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.

Still not happy with the way the engine feels or sounds, so I bought a set of plugs and went to change them today.

No need to go any further. Ordered a new set from Pelican but will not arrive till next week. Bummer. On the bright side hopefully replacing the coils and plugs will restore the throttle response and overall feel of the engine after sitting for a year. I don't guess they've ever been changed so after 12 years and almost 90k I guess it's time...
Sandersd,
Quick question, are those pics from the coils on the driver's side?

Actually it is from the driver side. But I figure if one is bad the others can't be far behind. I don't want to have to keep going back and changing them one by one every time one goes bad so I'll just change them all.

I was at around 95000 miles before change.

Was it missfiring? If not, then it could be jsut the plugs. Good time to replace the coils though. Mine looked worst than those. One started to missfire in wet so I covered it in RTV, it re sealed it and has been working like a charm ever since.
Feel/sound may be improved by new plugs/coils but the cracks visible in the pictures don’t mean that there’s something wrong w/them. I’ve seen worse looking coils work just fine.
Unless they are shorting out and not creating a spark, even when cracked they work just as well as a new one. The most likely reason people notice a performance improvement are because they change the plugs too. Now thise when they start to have a very large gap will decrease performance. However since most people change both, they think the coils made the difference too.
