I installed a Nitrous express Kit on my 2008 GT. Works Great. I want to change the plugs to some a bit colder as recommended by Nitrous express.
When I spoke with Nitrous Express they told me to run NGK's. I was also told to call NKG directly to ask which part number would work becaus ethe 2008 uses the "newer style" plug.
NGK told me to use their "NEW" plug part# 7554 which is an Iridium but the ONLY one made that is 1 heat range colder for the 2008 Mustang.
I went to install them and they are way too small, thread wise that is.
Do I maybe have an "early 2008" which uses the larger plugs like the 2007??
Any help would be great.
Thanks,
Jack
