Spark Plugs on an H3??? Schematics??

[H3.007]

Thanks for all of the responses. I spoke to a colleague at work who drag races professionally and he told me the same thing about the plugs - re: don't mess. I emailed the dealer today to find out the plug specs so I'll let everyone know about the response.

Also, if anyone knows about Stabilitrak issues, please see my posting from this evening - I am not getting any response from the button... Again, perhaps my innocent ignorance of having driven vehicles without such a function.

Thanks,
Chris
