I have a check engine light on 1998 Ford Expedition unfortunately it’s the problematic #3 cylinder on a 4.6 motor. So I decide to go for plugs and wires to start, NAPA web site have over 20 different plugs available Platinum, double Platinum, and Iridium at $12 dollars a piece. Has any one bought these? How much better are they? If I where to travel across ocean or to the Antarctic I would want the so called best or at least the most expensive? Ford claims to change plugs at 100k miles. If you wait to long the plug and aluminum head just about become one, and it you ruin it, big money fix. So maybe if Iridium plugs last forever it would be worth it I guess? Or it’s a marketing deal when I grew up there where about 3 different types of cereals Flakes, puffs or sugar flakes now they have a whole aisle.
