The plugs worked only okay for a little while. Then the 4.3L V-6 in my Chevy 1500 pickup started running rough after about 25,000 miles and I pulled a plug, and they were already needing to be replaced. The 4 prongs allows carbon to easily collect which led to plug fouling and bad spark. I took my truck to the shop and the mechanic told me to replace them with AC Delco Iridiums. I did so and the Iridiums put these to shame. Save the trouble and go with AC Delco Iridiums from the beginning.

Comments about Bosch Platinum+4 Spark Plug:
I had the Bosch Platinum-2 in my truck before, but after nearly a year and a half they were starting to wear out. I wanted more power, but needed better mileage. With prices in my area hovering just under $4 a gallon, any way to get more power but keep my gas mileage the same or better was huge. The Platinum+4 has given me that.
I've noticed a better acceleration, a quicker start, and a more complete fuel burn. Not to mention, better mileage. I'd say this was a good buy.
Pros
- Improves Engine Efficiency
- Increases Power
Cons

- Everyday Driving
Comments about Bosch Platinum+4 Spark Plug:
