spark plugs

What do you think of the condition of these spark plugs?

They look nermal - just used up.

I forgot that the gap size is part of the part number on NGK plugs. The -11 on the end is for 1.1mm or .040". They have a protector on the plug in the box so they don't get knocked around and change the gap. It doesn't hurt to check 'em, but I always found the few I checked spot on.

I think Sue only has about 65K miles. That means those Champions were put in not too long after it was new. I wonder why the originals got changed out so soon? That's assuming the originals weren't Champion.

I was wonderin' the same thing. A dealer owned mine for about first year, then 2nd owner was almost 5 yrs, then sat at used car lot for a while, then me 12/08. My guess is, since mine was bone stock, PO had a shop tell him/her they needed it & replaced them with the cheap stuff. It spent it's entire life in Washington DC/VA area so do harsh winters cause need for more frequent tune ups?? I have no idea.

Not to spark ( MAN, I am so effin' funny) another debate here, but I had to order my timing belt/ water pump replacement parts from Merlin the other day, so while I was at it I asked him about the spark plugs since they need to be changed too. He said that Denso's came in the VX originally so I had him send me what they use to replace the plugs in their shop. I figure since the original Denso's have lasted me almost 100k miles that they're good enough to go back in the old girl.
