Top = leading q no?

Pretty sure so anyways both leading were covered in oil looking deposits (Looked wet when I pulled em out)

The trailing were both LEAN as hell looking, like **** even afte rthe wire brush it didnt do much after mins of going at it.

Afterwards I didnt notice much of a diff but it seemed to back fire quicker pop pop hehe, anyways is that normal for old plugs or what could cause that or am I just worried?

rotor 1 and rotor 2's plug sets looked the same both bottom were lean, both top wet/deposits

thanks guys, im replacing them tmrw I'm just curious though

 

tops are actually trailing, and the bottoms are leading.

 

Oh ok

Then opposite what I wrote :P
