I've never dealt with plugs before but from what I know, these look fine. They're NGK Plat's.

 

They look good

 

They don't look bad but they're a little meh.

 

Why not replace them anyways, they're already out...

 

+1 no sense putting forth the effort to pull them and not replace them with brand new ones.

They look alright though. A new set will run you about $30.00 so I'd say just replace them.

 

The plugs been running to hot and now there life was shorten you will have to replace them. This happends when the car was running to lean or timing was advanced but you can check out the haynes manual it says it there.

 

^ Agreed.... The Haynes manual will show every way a plug can be just match yours up but i am like the rest since they are out mine as well replace them and go back with ngks, either platinum or ridum i have good luck with the ridum plugs but they are a bit more pricey

 

personally i say go with coppers for a smooth idle and acceleration and there cheaper.
NGK only for course
