What is wrong with these plugs? Thanks

 

they are overheated.

 

Holy lean batman!

 

do they have little blisters on the electrode too?

 

No blisters on the electrode and those plugs were only from 2 days of driving. Do you still think they are overheated?

 

Yes, you need to check that tune.

 

running to lean maybe?

 

If the car is tuned for ecconomy then id say those plugs are perfect. As long as you dont run high boost or do track work.

If economy is not your goal, they are running somewhat hot AKA lean (seen much worse and where the engine lived) but not to say problamatic.

Then again its like spittng in a hanky and sending it to your doctor to diagnose your problems....not enought to go on.
