These came from a '95 Vette with 89k on the clock. I'm not sure how long these have been in there but they don't look too good. I put some new TR55's back in it and boy was there an immediate difference. Completely smoothed the idle and it's much more responsive. What do you think of them? It is running rich as hell so that has played a large part in them looking crappy. I don't really know of anyone with LT1 so???are that can take a quick look at the tables and help me get it running better for the cost of about free, so I guess it's gonna stay that way.

The plugs are laid out as:
7 5 3 1
8 6 4 2

The plugs look worn, but not really that bad except for being darker (richness). At least the porcelain is not shattered on any one, or flecks of aluminum on them!

They aren't the worst plugs I've seen, but you can certainly tell it's running rich.

An LT1 that doesnt run rich is like a hooker that doesn't do tricks. Those dont look as bad as some of the plugs I changed on a couple of my buddies LT1 cars.

****, those look good for 89k LT-1 plugs. I'd put um back in and go another 50k. Stock Delco platinums F T W.

I would clean, re-gap and keep as spares.
