Need new spark plugs on my mondeo st200 and wondered if anyone in here can recomend any special plugs. Thinking of ngk iridium plugs or denso iridium plugs, but don`t know much about spark plugs.
Think my car is only running 5 cyllinders now, and did a fault code scan, and it came up with missfire on cyl 6. So that`s why I want to change the spark plugs.
