sorry really wanted to have it limited to the 2 choices. From what i found one of those plugs would be for 96-98 models and the other would be for 99-04. Im having the hardest time locating the spark plugs localy with the part numbers ive been finding in the usual forums.
Basicaly the car has a few of the normal bolt on's with exhuast. Going to run 75-125 shot. Its an 03 GT. Ive been tryn to search te forums but the part numbers im getting here arent matching up with the local auto chains.
One of the local national chains had one of the NGK plugs i listed, but not the other. Just want to make sure i get the right plugs. If you have any other options for a colder plug that might be a little easier to find or know which one of the 2 plugs i listed would be right for my car id be very appreciative for the info.
When I contacted Kenne Bell tech support about which plugs to use with their 9 psi intercooled kit in my 03 GT they recommended NGK TR6 plugs. When I went to sparkplugs.com I noticed this is the same plug for use in the 04 cobra. Try going to sparkplugs.com and see what they have that might fit your application.
thats where i got the part numbers ive been using to look for plugs. either the part numbers are wrong or the 3 local auto stores i went to looking for them are staffed by morons.
