Review on Autolite APP605 4PK Double Platinum Spark by Tyrone Carter

The 3.8 liter V6 engine in our 2002 Mustang required new spark plugs and the recommended Motorcraft spark plugs were no longer available. This ignition system is unique in that the spark plugs on the driver's side are reverse polarity meaning the energy flow is the opposite of what is standard for most ignition systems such as. B. Coil on plug. Either way, the answer lies in using these dual platinum connectors. Ford used to own Autolite, and Motorcraft spark plugs are also made in Mexico, so I think they're actually part of Motorcraft too. With new spark plugs the car runs much better. The old ones are badly worn on the driver's side.
