Replying to Topic 'Spark Plugs n Wires?'
The only plugs you want to use are the Autolite/Motorcraft Double Platinum plugs.
Duratecs come with a Motorcraft AWSF32PP which is the exact same plug as the Autolite APP764. Anything else and the Duratec eats them like candy. Most people who use other plugs experience misfires, fouled plugs, and shortened plug life.
And aftermarket plugs and wires don't make much HP (if any at all). The gains people see from aftermarket ones usually comes from replacing old, worn out wires with the aftermarket ones, not from the "better" wires. However, the Ford Motorsport 9mm wires are about 1/2 the price as the stock wires are, so when your stock wires get worn, those are a good choice for replacment.
