Default Spark Plugs replaced

I've just replaced my spark plugs. The car has low mileage considering replacement is to be done at 100,000km/60,000M. My car has 87,236KM or 54,205M. I know it's early but I'm a bit excessive when it comes to maintenance. I drive my car hard so I like peace of mind. The job took me a few hours taking my time to do it right without breaking anything. The most difficult to replace for me was the drivers side closest to the firewall. Here are some pictures of the plugs. Sorry for the poor quality pics as they were taken on an Iphone.

They still look ok. Would probably last another 20k miles or longer. The electrodes look intact and showing normal wear.

The textbook calls for fresh plugs at 60K miles...

Although I did mine at 80K miles.. (Time Issues) I will be doing the next set at 140K miles..

Mine looked better except for the rear 2, which show signs of oil seeping into the thread.. More than likely from the spark pug tube seals..



I found this thread to be the most helpful..
