    Replaced with NGKs gapped to 0.040 - let's see what it does to mileage and go power.

    Upwards of +1 mpg I'd guess. Probably sounds a little better too. On the bright side they look they've been burning correctly.

    Yeah, feels and sounds better. I was very pleasantly surprised at the uniformity of the wear on old plugs, though, and other than the NGK side being noticeably tighter, there was nothing that really concerned me about any of what I saw or felt.
