Excessive wear on Spark plug 2 & 4
Not sure if you guys noticed. I just pulled out my Denso Iridium plugs and noticed heavy wear on plug 2 & 4 (the plugs where the coils are over it, 1& 3 have just plug cables).
I'm surprised to see a nice cave-in in both plug 2 and 4.
Any one experience similar wear?
NOTE: These plugs had covered 20k km

Sure you didnt squeeze too hard with the pliers when you were gapping them?
That is weird. I just checked mine the other day and they did not have an indentation, if anything I remember a slight bump where the electrode spark would contact the metal surface. Not sure though...

Nope, I didn't even gap them .... but since it's consistent on both plug 2 and 4, I can only speculate that those plugs under the ignition coil are receiving a much strong spark that 1&3 which are on plug cables.
