Hi, i have an 02 dakota with a 3.9. It has k&n intake with flowmaster super 40. Also with superchip. I put bosch platinum plugs in it yesterday and was making sure that these plugs were ok for it. i have heard the autolights were the best, but the store didnt have any in stock and it would have taken a week to get them. i am just making sure that the bosch platinums were ok to use. thanks

 

So long as they're the correct heat range and reach, they'll be fine. I personally don't like platinum plugs, because I think they're a waste of money. I prefer copper, and I just change them regularly.
