No, it is not necessary to change the spark plugs on your 2003 Ford Winstar at 30,000 miles. It has Platinum Plugs from the factory and they have a life span of approximately 100,000 miles. I suggest checking the gap and cleaning them at 50-60M miles, but not replacing until around 100K.
i run 40-1 in mine but thinking of 50-1 spark plugs were a bit dark
It's usually recommended every 50 to 60 thousand miles.
