you might get different choices here since there is plenty of those on the market. I have used SplitFire plugs and wires in my truck and I'm happy with them..... mine has crossed 100K mark though.

Later,

Just my opinion

Did the Bosch Platinum + 4's do much for gas mileage?

I've got SplitFires but wouldn't tell you if it improved anything as far as milege since I've put my KKM at the same time too. It runs smoother now it seems though and starts right up....
