Very surprised to see the restrictive rules for new members participating and creating discussions. I see it is purposeful, but it seems to me to be beyond almost any other car forum, for instance miata.net, etc. That said, this is a good resource.

I am looking at a 2009 RX-8 with 31,000 miles. I am waiting for a compression check. In the meantime, the plugs were changed. Can anyone comment on this photo of the plus taken out, and how this might relate to engine condition?

Can these be typical plugs for a 31,000 mile car? Or are these out of the ordinary for a an original set?

Thanks, Steve K.

 

It is that way because anything anyone can think of starting a discussion on, has already been discussed, and the answers anyone seeks are already here.

And those plugs are a little gunked up but depending on how the car was driven and what gas was used in it, it looks pretty normal if it is on the original ignition coils.

 

The plugs appear to have normal deposits on them. Does not appear that the owner was premixing though. Its hard to see if the electrodes are worn but I wouldn't keep a set of plugs in my 8 for 31k anyways.
