I have the Bosch plugs in my Ford Ranger. I was hoping to get slightly better power and mileage but I have seen no improvement. I may even have had a slight decrease in gas mileage. It is hard to tell especially since I wasn't tracking gas mileage very carefully. I have been thinking about changing to a more conventional style plug and indexing them as described somewhere on this site. My plugs are a pain to get to so I am in no hurry.
