Hi,
Can anyone help me with the part number of a 1 Heat Range Colder Champion spark plugs for a GT?I couldn't find any post and i need to buy the right code please.
Thank you
I'm pretty sure there isn't one. Autolite HTO is one heat range colder and Brisk 3VR14S is one heat range colder. I'm pretty sure those are it... and Brisk is one piece if that is why you are interested in a colder plug.
We dont have FRPP or Brisk or Motorcraft in Lebanon so Champion is the option i have, i am going nitrous with the car (GT 2005) so ill be needing a -1 spark plug.
