Ok, so everyone and anyone is telling me to get "Motorcraft AGSF-32C" sparkplugs, but I can't find anywhere to buy them. I even called the local Ford dealership. If anyone knows where to get these spark plugs or any other spark plugs that would work well please let me know what and where to get them. Also nooo platinum plugs and I only want single prong. Thankyou.
I run ngk TR6 plugs, they are 1 range colder than stock. stock plug for gt40 heads = a TR5 one range colder for a gt40 head = TR6 2 ranges colder and you have to run an Irrid. plug that is like a TRi7 or TR7i or something. I had a HUGE PITA deal getting the correct plug at 1 range colder. I finaly got NGK's phone number and called. They were 100% helpfull. I have had good resluts with NGK plugs from cars to bikes. The autolight plugs are great too, I just was done with trying to get a damn part and had what I needed for a NGK plug and ran.
