Pls read these plugs

According to maintenance history these plugs were replaced 23K miles ago.

The broken one is Leading. I am afraid to replaced the other two, it took 90 minutes to remove the Leading from rear rotor...

Dyno sheet show plugs were bad...215 rwhp.

Should I replace the other two?

Replcae them all, that should not even be a question considering the price. I could see not doing it if they were like 40 bucks a piece.

Agreed. At <$5 a piece and with 23K on the plugs, there is no question whether or not to replace them.

the broken one looks wet due to WD40...the other one look weird like lean/rich...I will replace the other two (not afraid about cost).

What is the problem if you have oil on the spark plugs? Just wondering because mine looked a little wet last time I changed them.

got the other two removed...10 minutes. All done with just the elbow removed.

These two are very similar to the other...Trailing plug show grayish/black while Leading show fouled full of black carbon.

I'm interested too. Both of my leading plugs( on my last change ) seemed to have extra oil on the threads....
