I have been having major issues with the plugs I put in lately. I put in motorcraft and they worked great for about 300 miles. Now I am being told these plugs are not very good and I want to swich to a good plug. Im finding inconsistent information everywhere I look and I cannot find the right plugs to use. Apparently the svt requires very specific spark plugs and a specific gap. Does anyone know what plugs work best and the gap required for them? Thanks a bunch!
