I got a set of Motorcraft sparkplugs from the dealer and it seems that the dealer does not carry the double platinums any longer. The new part number is AGSF-32F-MF4 (fine wire platinum) instead of AWSF32-PP. Should I return them and get Autolites? Sparkplug Design
The fine wire are the new supercede of the double plats . They allow the plug to spark at lower voltages/amps . They work well . Yes the V8SHO link is good info -I've talked with Paul about this also .
