Message	range, the 6 is the heat range. It looks like Z1 is using the laser platinum plugs, which it seems NGK recommends for the TT. It just sounds like the IX plugs are built for more race type engines when reading NGKs site. If someone has nissan OEM plugs I would like to know how they size up to the NGK plugs. I have been told the NGKs are shorter and this makes me nervous. "Do you guys put the key in "balls down", or up?" -BobbyT 10:28:19 03/06/09
