As I wrote elsewhere, I replaced the spark plugs on my 98 Legacy OB. I noticed that the old plugs wore unevenly, with #3 and #4 being in much worse shape than #1 and #2. Here's the picture.

 

Does that mean anything, or is just normal wear?

Yes, that could be caused by a few engine ''problems'', including how tight the engine is in the compartment. It seems ''someone'' was complaining about that in http://www.ultimatesubaru.org/forum/showthread.php?t=106459 :). Maybe only the front two plugs got changed the last time because the rears were considered too hard to get to by whomever did the work.

:lol:

 

Well, that would make sense as to why the "rear" 2 plugs were practically gone. Haven't really thought of that.

 

That said, the plugs are all NGK's double platinums, so assumed that they replaced them all at the same time.
