Yes NGK but.... I'm looking for the temp range in the JDM ITR motor. I know the USDM uses the PFR6G-11 and is 10.6:1

The JDM ITR is 11.1:1. Does it use the PFR7G-11? (one range colder) Or does it use the same plug as the USDM motor?

I'm asking beacuse I have a GSR block with USDM pistons and a ITR head (11.1:1) and want to make sure I am using the correct plug.

Thanks for the help.

 

bump i want too know too

 

PFR7G-11

 

Yeah, my '97 had those in it. Thing is, I couldn't find those plug sto save my life. I used BKR7EVX-11 instead. Those are platinums and there's also a copper plug you can use. Try http://www.clubplug.net/.
