NGK V-Power plugs work fine, but no better than standard copper plugs IMO. If your old ones are spent, then new plugs of any kind will be an improvement. Don't overlook the air filter as a maintenance item. Depending on the mileage, a new oxygen sensor could improve economy too.
Personally, I would not use anything like SeaFoam, especially if you don't plan on replacing the O2 sensor. I think the water mist method carries less risk and is definitely cheaper for doing the same thing. If I was going to use
anything in the same category as SeaFoam, it would be Motorcraft PM-3. Unlike SeaFoam, it's a lot more than just rubbing alcohol and mineral oil and it's used internally by Ford.
