James...most folks are running these...

I'm running 2 steps colder myself (last one)

Also...some have ran the SRT plug as well but I've read on here they are too long (?)...I can't verify that though but looking at the web site http://www.sparkplugs.com the Champion plugs are 1 inch where as the NGKs are .984.

The two listed above are the correct length for the Ecotec though I know that!


Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
